Unless they’ve forgot 2010, I don’t think you have to worry about the Republicans repealing (at least parts of) it.
However, to win they’ve got to say more than just “repeal”. Many people won’t accept nothing in exchange.
They’ve got to sell Conservative principles and the solution to the Healthcare problem.
That’s not to say they have to promise pennies from heaven; although many would expect that.
They have to prove WHY it’s the best for the country and the people. They have to become teachers. And if all they’re going to do is spout talking points, then it’s going to get them nowhere.
I think I should worry a lot. The Pubs won't repeal anything. Show me any taxes the congressional class of 2010 repealed. When push came to shove Boehner folded like a paper bag every time.
