Can support for deeply unpopular policy ideas sink the GOP?

It seems the policies of the Republicans are hugely out of step with the majority of Americans in yet another major respect. Almost all of them nowadays talk openly of essentially ending Social Security. If that isn't enough to take the blinders off a good number of voters' eyes, I honestly can't think what would be. I am truly fearful that the rush to full-on fascism may be unstoppable. But deeply unpopular changes in laws that negatively affect almost everyones' lives could be what does it. 

Once again, though, Democratic messaging needs to be greatly improved. They talk about "removing it from mandatory spending" and "Congress reauthorizing spending." But what they mean is first deep cuts, then elimination through phony privatization. There is a close parallel. The Pinochet government in the 1970s in Chile did exactly that to Chile's social security system. We all remember when George W Bush tried this, and it was one of the things (in addition to an increasingly unpopular foreign war) that sunk his presidency and allowed Democrats to regain legislative power. The situation today is different, but not entirely so.
