Yet Another Thing I Don't Get

So after finally realizing that the country ain't with them on this idea of revamping Medicare, Republicans in Congress are now saying they won't be pushing for that. Trouble is that without that, the Paul Ryan plan (which they all voted for or support) isn't worth very much.

I don't get this. I mean, they do polling and they're supposed to have a reasonable idea of what will and won't fly with the electorate. You and I have long known that a plan which pays a lot less towards Medicare isn't going to fly with most of this country, especially if at the same time you're cutting the taxes of the Koch Brothers. How come the leaders of the G.O.P. didn't know this? Didn't anyone tell them they don't control the Senate and the White House? And that even if they did, passing this would be a good way to lose both?
