He notes, correctly, that the GOP isn't dead, but the long awaited crack-up with movement conservatism is here. An exerpt:
Movement conservatives began to take over the party under Goldwater and then launched the Reagan Revolution. They have controlled the party ever since. But as Pat Buchanan proved, as the baffling primaries of 2012 proved and Donaldus Magnus now proves, the appetite for doctrinaire conservatism is waning, even among Republicans.
Trump has never embraced the social conservatism of many rank-and-file Republican voters. How will they respond to Trump shrugging off the Great Bathroom Panic of 2016? Trump rejects the arguments of free trade and saner immigration laws, alienating the Wall Street wing. Trump's foreign "policy" is already causing defections among neoconservatives.
I can understand the appeal of Trump to certain segments of the electorate. But I wonder how much certain constituencies within the GOP can stomach Trump. And where will they go?
I had a few ex-students lamenting that they finally get to vote for President, and they have no one to vote for. A canny politician with Libertarian leanings might be looking at that ballot slot right about now.
Overall, the GOP that emerges from this election will be very different than the one that elected two Bushes. As a Democrat, I am glad, but more importantly as an American, I fear what may emerge.
