Realisticly, that is very doubtful.
One of the big problems that the conservative movement has facing it, is that they have been completely devoid of new policy ideas since the 1980s. Everyone of the 17 republican candidates last year, with maybe a slight exception for Paul, ran on the exact same platform that Reagan ran on in 1980…big tax cuts, big military spending, and anti abortion. When a political movement is that devoid of new ideas, the old ideas become rigid dogma, and the radical fringe elements start to pervert them for their own means in order to infiltrate the power base.
So while republicans may be offended by the notion that their party is the American Nazi party, they still offer up nothing to avert that, no new ideas to replace ideas that have been their stock in trade for 40+ years. In their case, this is made all the worse because they have been practicing tactics…aka the Southern Strategy as one example…for even longer that specifically target these groups to BECOME part of the GOP.
