Washington (CNN) Republicans are considering their next step now that many Democrats are planning to filibuster the nomination of Supreme Court nominee Neil Gorsuch.

The Senate Judiciary Committee voted Monday to send Gorsuch's nomination to the full Senate. The vote was along party lines, 11-9.

Republicans, who number 52 in the Senate, were unsuccessful in securing the eight Democrats to join them in order to end the expected filibuster, or in more technical terms, invoke cloture.

However, the majority party can still get around it by changing the rules and requiring only a simple majority, or 51 votes, to end the debate.

So far, only four Democrats -- Sens. Joe Manchin of West Virginia, Heidi Heitkamp of North Dakota, Sen. Joe Donnelly of Indiana and Sen. Michael Bennet of Colorado -- have said they are planning to vote to advance Gorsuch's nomination.

Monday afternoon during the judiciary hearing, Sen. Chris Coons of Delaware became the 41st senator to say he plans to filibuster, giving Democrats enough votes to sustain the debate. By Tuesday afternoon, 44 senators had said they would oppose cloture on Gorsuch's nomination.

Republicans are preparing to launch the rule change, which is also known as the "nuclear option," a controversial move that Democrats took more than three years ago for all judicial nominees other than Supreme Court justices.

Here's what Democrats have said about Gorsuch.

Democrats who will vote for Gorsuch:

1. Sen. Joe Manchin (West Virginia) -- "I will vote to confirm Judge Neil Gorsuch to be the ninth justice on the Supreme Court." -- Tweet and statement from 3/30/2017

2. Sen. Heidi Heitkamp (North Dakota) -- "After doing my due diligence by meeting with Judge Gorsuch and reviewing his record and testimony before the Senate Judiciary Committee, I've decided to vote in favor of his confirmation." Statement from 3/30/2017

3. Sen. Joe Donnelly (Indiana) -- "After meeting with Judge Gorsuch, conducting a thorough review of his record, and closely following his hearing before the Senate Judiciary Committee, I believe that he is a qualified jurist who will base his decisions on his understanding of the law and is well-respected among his peers." -- Statement from 4/2/2017

Democrats who won't filibuster

4. Sen. Michael Bennet (Colorado) -- "Using the filibuster and nuclear option at this moment takes us in the wrong direction. I have spent the past several weeks trying to avoid this outcome. Changing the Senate rules now will only further politicize the Supreme Court and prevent the Senate from blocking more extreme judges in the future. I will oppose efforts to filibuster the nomination, and strongly encourage my colleagues not to use the nuclear option." -- Statement on 4/3/2017

Democrats who plan to filibuster:

1. Senate Democratic Leader Chuck Schumer (New York) -- "My vote will be 'no'. ... To my Republican friends who think that if Judge Gorsuch fails to reach 60 votes, we ought to change the rules, I say: If this nominee cannot earn 60 votes, a bar met by each of President Obama's nominees, and President Bush's last two nominees, the answer isn't to change the rules, it's to change the nominee." -- Statement on Senate floor on 3/23/2017

2. Independent Sen. Bernie Sanders (Vermont) -- "After careful consideration of Judge Gorsuch's record, I have concluded that I will not vote to confirm him to be an associate justice of the Supreme Court, and I will not support Republican efforts to change the rules to choke off debate and ram the nomination through the Senate." -- Statement on 3/23/2017

3. Sen. Bob Casey (Pennsylvania) -- "I don't believe that Judge Gorsuch, his judicial approach, would ensure fairness for workers and families in Pennsylvania and indeed across the country, and I will not support his nomination. ... If you seek to become a justice of the Supreme Court ... you ought to be able to rack up 60 votes ... I think that's the standard you should be able to meet." -- Press call with reporters on 3/23/2017

4. Sen. Ron Wyden (Oregon) -- "I will vote no on his nomination and I will vote to sustain a filibuster." -- Statement on 3/23/2017

5. Sen. Patty Murray (Washington) -- "After careful consideration, I will be voting against the nomination of Judge Neil Gorsuch, and I will oppose a cloture motion ending debate." -- Statement 3/24/2017

6. Sen. Elizabeth Warren (Massachusetts) -- "I believe Judge Gorsuch's nomination should be blocked." -- Op-ed in the Boston Globe on 3/20/2017

7. Sen. Jeff Merkley (Oregon) -- Merkley has long been supportive of the filibuster and reiterated that on Twitter on 3/29/2017. "I will not stand idly by and allow the people's government to be stolen. We must restore our #WeThePeople democracy and #StopGorsuch."

8. Sen. Tom Carper (Delaware) -- "Ultimately, I believe that moving forward with Judge Gorsuch's nomination will send a signal that it's acceptable to put partisan politics over fidelity to our Constitution. It is not. While I do not believe that two wrongs make a right, I believe this may be our only opportunity to right a historic wrong. Therefore, I am left with no other choice but to oppose Judge Gorsuch's nomination until we find agreement on moving Judge Garland's nomination forward at the same time." -- Statement on 3/29/2017

9. Sen. Tammy Baldwin (Wisconsin) -- "President Trump and his nominee need to earn 60 votes in the Senate," said Baldwin. "I will not be one of them." -- Journal Sentinel article on 2/2/2017

10. Sen. Bill Nelson (Florida) -- "I will vote no on the motion to invoke cloture and, if that succeeds, I will vote no on his confirmation." -- Statement on 3/27/2017

11. Sen. Cory Booker (New Jersey) -- "This is going to be a real test. I'm not sure what's going to happen, but I'm going to oppose Judge Gorsuch every step of the way. A 60-vote threshold is not something new for Supreme Court nominees to overcome. It helps ensure that presidents seek nominees whose views are in the mainstream." Interview with NJ.com on 2/5/2017

12. Sen. Mazie Hirono (Hawaii) -- "I have concluded that I will not be supporting Neil Gorsuch for this opening and so I very much support a 60-vote threshold." -- Interview with Wolf Blitzer on 3/27/2017

13. Sen. Tom Udall (New Mexico) -- "Every recent Supreme Court nominee has received at least 60 votes either for cloture or confirmation. Judge Gorsuch will be subject to the same test, and therefore, I will vote no on his confirmation, including cloture." -- Statement on 3/24/2017

14. Sen. Jack Reed (Rhode Island) -- "I will vote no on cloture and no on his nomination." -- Statement on 3/24/2017

15. Sen. Chris Murphy (Connecticut) -- "I will oppose both cloture, and if necessary, final passage, on Judge Gorsuch's nomination," Murphy wrote in a post on Facebook 3/28/2017

He has also expressed some support for sustaining the filibuster. "Yes I am not for changing the rules of the Senate on Judge Gorsuch's nomination. Whether we like it or not, the rules of the Senate requires 60 votes for closure and that shouldn't change for Gorsuch. It's been the case for every other vote that hasn't been exempt for that requirement." -- To reporters on 3/27/2017

16. Sen. Sheldon Whitehouse (Rhode Island) -- "Judge Gorsuch needed to convince me he would not join the posse that has relentlessly stretched the law to benefit Republican partisans and corporations at the expense of everyone else. He did not. He will not get my vote." -- Statement on 3/24/2017

He also told reporters on 3/27/2017 that he will vote "no" on cloture, meaning he will be part of the filibuster.

17. Sen. Tim Kaine (Virginia) -- "Judge Gorsuch's selective activism in restricting women's rights and his framing of women making their own health decisions as 'the wrongdoing of others' are jarring and do not demonstrate a philosophy that belongs on the Supreme Court. I will oppose his nomination." -- Statement on 3/29/2017

He has also expressed some support for sustaining the filibuster. "The way I look at it is the Supreme Court is the only position that requires you to get to a 60-vote threshold, which means it mandates that there be some bipartisanship and that is appropriate. Life tenure. Highest court in the land. Should have to get to 60 votes." -- To reporters on 3/27/2017

18. Sen. Kamala Harris (California) -- "Exactly yes," Harris said when asked by David Axelrod for "Axe Files" whether she's urging Democrats to force supporters to produce 60 votes.

Harris has also said she won't vote to confirm Gorsuch. "I cannot support his nomination." -- Op-ed in San Francisco Chronicle on 3/24/2017

19. Sen. Al Franken (Minnesota) -- "Earlier today, I sat down with WCCO's Esme Murphy and announced that I will be voting no on Judge Neil Gorsuch because I fear he'd be a part of a U.S. Supreme Court that would put the interests of large corporations before Minnesotans and all Americans." -- Statement on Facebook on 3/26/2017

20. Sen. Debbie Stabenow (Michigan) -- "After carefully reviewing his record and listening to his testimony last week in the Senate Judiciary Committee, I have concluded that supporting the nomination of Judge Neil Gorsuch to the United States Supreme Court is not in the best interests of the people of Michigan whom I am proud to represent." -- Statement on 3/28/2017

A spokeswoman for Stabenow confirmed that the senator will also vote "no" on cloture.

22. Sen. Chris Van Hollen (Maryland) -- "After the Senate's unprecedented abdication of constitutional responsibility with respect to the Garland nomination, we must begin to restore faith in the Supreme Court. That requires a nominee who is widely viewed to be an impartial administrator of justice - someone who is truly in the mainstream and who can earn the support of at least 60 senators. I will insist that this nominee be held to that standard." -- Statement on 3/28/2017

23. Senate Minority Whip Dick Durbin (Illinois) -- "I don't know the answer to that. ... I just announced that I'll be voting against Gorsuch and for the filibuster -- basically require 60 votes." -- To reporters on 3/28/2017

24. Sen. Jeanne Shaheen (New Hampshire) -- "After meeting with Judge Gorsuch and reviewing his record and testimony, I cannot support his nomination to serve on the Supreme Court .. .As Judge Gorsuch's nomination comes to the floor, I will support a 60-vote threshold for approval, an appropriate high bar that has been met by seven of the eight current Supreme Court justices." -- Statement on 3/28/2017

34. Sen. Catherine Cortez Masto (Nevada) -- "I believe that a nominee of such importance should gain 60 votes to be confirmed.

35. Sen. Claire McCaskill (Missouri) -- "While I have come to the conclusion that I can't support Neil Gorsuch for the Supreme Court — and will vote no on the procedural vote and his confirmation — I remain very worried about our polarized politics and what the future will bring, since I'm certain we will have a Senate rule change that will usher in more extreme judges in the future." In a post on Medium, 3/31/2017

36. Sen. Sherrod Brown (Ohio) -- "The people of Ohio deserve Supreme Court Justices who will defend the rights of working families over Wall Street and corporate special interests -- and Judge Gorsuch's record doesn't pass that test. I cannot support any nominee who does not recognize that corporations are not people." -- Statement on 1/31/2017

Brown's office confirmed on 3/31/2017 that he is also voting no on cloture.

37. Sen. Jon Tester (Montana) -- "Judge Gorsuch is a smart man, but that doesn't make him right for a lifetime appointment to the U.S. Supreme Court. I cannot support a nominee who refuses to answer important questions. With Judge Gorsuch on the bench, I am deeply concerned that dark money will continue to drown out the voices and votes of citizens, the court will stand between women and their doctors, and the government will reach into the private lives of law-abiding Americans. These are not Montana values, which is why I cannot support this nomination." His office also said Tester will be voting "no" on cloture as well as on final passage. -- Statement on 4/2/2017

38. Sen. Dianne Feinstein (California) -- "Unfortunately based on Judge Gorsuch's record at the Department of Justice, his tenure on the bench, his appearance before the Senate and his written questions for the record, I cannot support this nomination." -- At the Senate Judiciary Committee hearing on 4/3/2017. Her spokesman clarified that she will oppose cloture as well.

39. Sen. Mark Warner (Virginia) -- "I have hoped that bipartisan efforts would result in a better way forward, instead of Republicans threatening to impose the 'nuclear' option. But such a threat is not alone reason enough to support a nominee who has not provided the Senate with sufficient assurances regarding his approach and judicial philosophy. Consequently, I plan to vote against cloture and against his confirmation." -- Statement on 4/3/2017

40. Sen. Pat Leahy (Vermont) -- "I will not and cannot support advancing this nomination." -- At the Senate Judiciary Committee hearing on 4/3/2017

41. Sen. Chris Coons (Delaware) -- "I am not ready to end debate on this issue, so I will be voting against cloture unless we are able as a body to finally sit down and find a way to avoid the nuclear option and ensure the process to fill the next vacancy on the court is not a narrowly partisan process, but rather an opportunity of both parties to weigh in and ensure we place a judge on the court who can secure support from members of both parties." -- In judiciary committee hearing on 4/3/2017

42. Sen. Ben Cardin (Maryland) -- "I'm voting no on cloture b/c I don't believe #Gorsuch would be an independent check on @POTUS, who has tested the Constitution like no other" -- in a Tweet on 4/3/2017

43. Sen. Bob Menendez (New Jersey) -- "The last four judges confirmed to the Supreme Court received more than 60 votes in the U.S. Senate, and there is no reason that Neil Gorsuch shouldn't be held to the same standard. Instead of changing the rules on lifetime appointments that have made the Senate the greatest deliberative body, we should instead work together in a bipartisan manner to find a nominee who is capable of winning a healthy majority in the U.S. Senate." -- statement on 4/3/2017

44. Independent Sen. Angus King (Maine) -- "Although there could be circumstances where it might be appropriate to support cloture and then vote against the nomination, the current status of this procedure does not strike me as such a case. If I am opposed to this nomination, it seems logical to oppose cloture because under the current rules, this would defeat the nomination. To support cloture in the current circumstance would make me guilty of 'complicity', to borrow Judge Gorsuch's memorable term." -- statement on 4/4/2017
