Thank you for your thought provoking comment.
Here is a are some thoughts : the Republicans welcomed, with open arms, the Dixiecrats in 64 & 65 , with the passage of the Civil Rights & Voting Rights Acts. These men became the backbone of Nixon’s ‘Southern Strategy’ and ‘Silent Majority’ sloganeering political kitsch. Look to Reagan’s ‘I believe in States Rights’ declaration at the Neshoba County Fair speech, that opened his 1980 campaign.
Look to Newt Gingrich’s ‘Contract with America’ and then the rise of the ‘Tea Party’ Jacobins: recall that Eric Cantor was supplanted by the even more hysterical radicalism of Dave Brat? That Tea Party coterie became the Republican Party. But Trump takes the cake, the Republicans simply surrendered, in the slow stages of political cowardice, one by one: McConnell’s wife got an appointment to a Cabinet level post, while still maintaining her corporate ties! While Mitch opined about ‘mule piss’ , celebrated in the pages of this newspaper by Janan Ganesh? This a record of absolute surrender , exercised in halting stages, to political irrationalism. One question: where are the Eisenhower Republicans? Colin Powell come to mind, he voted for New Democrat Obama.
