President Donald Trump is "determined and committed" to getting "tax cuts" and with the Senate gridlock caused by three Republicans against Trump, the administration will target four vulnerable Democrats in heavy Trump states, according to conservative economic analyst Larry Kudlow.

"I think the president is absolutely determined and committed to get this done," Kudlow told host John Catsimatidis on Sunday's "The Cats Roundtable" on 970 AM-N.Y. "I was in with him a few weeks ago, and I saw it is different than healthcare, John. He is absolutely committed and determined to get it done."

The GOP's plan to repeal and replace Obamacare failed this summer by one vote, notably Sen. John McCain, R-Ariz., a Never Trumper. Two other Senate Republicans Sen. Susan Collins, R-Maine, and Sen. Lisa Murkowski, R-Alaska, also voted against the bill.

Trump cannot count on those three in tax cuts necessarily, so with a narrow 52-48 majority in the Senate, the White House will target Senate Democrats who are vulnerable in heavy Trump states in the 2018 midterm elections — West Virginia, Indiana, Montana, and Missouri — according to Kudlow.

"The Trump states want tax cuts, and the Democrats, four Democrats are vulnerable, that tells you a lot, and I'm going to say Trump is very committed," Kudlow added. "Remember he singled our Claire McCaskill at his speech on Wednesday. Missouri wants Trump tax cuts . . . She better beware, it's going to be a tough vote."
