Is there a way for the Republican Party to cut Trump loose as their leader? Make Trump stand as an independent and not enable him to run as a Republican candidate in the next election?
In answer to your questions, Bogie, absolutely not. Republicans knew what they were getting when President Trump won their party's nomination in 2016. Some prominent members of the party backed him in the election. Many others disavowed things he said on the campaign trail. They said they weren't voting for Hillary Clinton, but they also could not support Donald Trump. In light of his disappointing re-affirmation of support of White Supremacists, White Nationalists, and Neo-Nazis, there have been numerous Congressional Republicans once again stating their disdain for what he said at Tuesday's press event in New York City. These are the same people that criticized him last year, yet they approve of his agenda, by and large.
If America did a re-vote of the 2016 election today, with no campaigning and no ads run, and the candidates on the Presidential ballot were exactly the same as last November, there is no doubt in my mind that the results would be the same. Trump would win the same 30 states he carried in the Fall. Clinton would win 20 states and the District of Columbia. The raw vote totals might be different, but the overall result would be unchanged. The traditional Republicans are seemingly between a rock and a hard place because of Donald Trump's words and actions, but when push comes to shove, they will continue to win elections, because they still espouse exclusion of minority populations in this country. Look at the makeup of their conventions. Republican delegations are about 95% white. The Democrats are much more diverse with inclusion politics. While Republicans would say such a disparity of diversity is not good for their party and they'd very much like to improve their appeal to other ethnic, racial, religious, and sexual orientation minorities, as long as they continue to win elections on the strength of rural, white voters who generally have high turnout rates, they are perfectly fine with the status quo.
Voter suppression laws enacted in many states between the 2012 and 2016 elections have apparently worked their magic, and these changes were implemented by Republican state legislatures who were appalled that America had the gall to elect a mixed race President in 2008 and re-elect him in 2012. For all the blowback President Trump is getting from members of his own party today, all will be forgiven and forgotten when 2018 rolls around. Many of the pundits say, "but this time, it seems different...." Sorry, but I don't buy that assertion at all.
