Red state Democratic senators aren’t exactly lining up behind Minority Leader Chuck Schumer in his fight to stop President Trump’s nomination to the Supreme Court.

Several said they were determined to make up their own minds as they weigh the political consequences back home before deciding whether to support Brett Kavanaugh to replace the retiring Justice Anthony Kennedy.

“I’ll be 71 years old in August, you’re going to whip me? Kiss my you know what,” West Virginia’s Sen. Joe Manchin told Politico.

Schumer faces intense pressure from the left to thwart Trump’s nominee, who would move the court to the right and, critics fear, threaten Roe v. Wade and LGBTQ rights.

But Schumer also has six vulnerable members in his caucus from red and purple states up for re-election this fall.

To defeat Kavanaugh, Schumer has to keep all 49 of his members in line and convince at least one moderate GOP senator, such as Maine’s Susan Collins, to switch teams.

But it could prove impossible for Schumer to persuade senators like Manchin, Heidi Heitkamp of North Dakota and Joe Donnelly of Indiana to vote against Kavanaugh, according to the website.

All supported Supreme Court Justice Neil Gorsuch last year, and all three said their decision won’t be swayed by Schumer no matter what he does this year.

“My decision won’t have anything to do with Chuck Schumer,” Donnelly said.

“I’m going to vote the way I’m going to vote regardless of what the leader says,” Heitkamp told the website.

And even Democrats concede that the New York Democrat has an uphill fight.

“The worst thing you can do is to try to strong-arm a resilient, experienced, independent senator from a red state,” said Sen. Brian Schatz of Hawaii, a member of the whip team, which is charged with preserving party unity.

“It just wouldn’t work to try to break arms. They wouldn’t respond well to that.”
