But in our interview Sunday night, Castle pointed out that there are important areas where he agrees with conservatives, such as repealing Obamacare and making the Bush tax cuts permanent.

“I did not vote for any of the health care legislation,” Castle said. “I had a vote in committee: voted no. I had a vote in the House: voted no. And I had a vote on the final version, and again voted no.”

“So, I have signed on to the Herger legislation which will substitute the Republican bill for the Obama bill in health care,” Castle continued. Mike Pence, a conservative stalwart from Indiana, is among the bill’s cosponsors.

But what if Republicans were to bring up a bill to simply repeal Obamacare, without attaching it to replacement legislation?

“The whole idea of that even coming up [in the next Congress], I think, is beyond reality at this point, unless, obviously, Republicans take over the House and the Senate,” said Castle. “I would look at it. I would consider it. On the other hand, I would also consider trying to improve what was passed in order to provide better health care to people. So I’m not saying absolutely no to anything at this point. The only thing I’m sure of is, I’d replace the Obama bill with the Republican bill.”
