Take a Memo:
Serious question posed in the thread's title to Trump supporters who are (mostly) republicans and even some right-leaning democrats.
So, given the very real fact that Trump is turning AGAINST the republican led congress while still deriding democrats such as Obama and Clinton, AND given that he is finding it a bit more difficult than expected to drain that proverbial D.C. swamp, Trump may opt to resign and perhaps start a uniquely trump-like 3rd party.........
Would current Trump backers follow him were he to do so?
Interesting question to ponder.
I think we have to objectively look at who makes up "Trump supporters" or who voted for him in 2016. There are always outliers and exceptions but I think we can safely break them down into three basic categories. 1) People who were simply opposed to Hillary Clinton. 2) People who don't trust The Establishment body politic in DC. 3) The Nationalist-Populists.
I think #3 are his die hard supporters and they are solid. #2 are a precarious group who could become disillusioned with Trump if it seems he is becoming aligned with the establishment. #1 is the real bugaboo. Many voted for Trump because he wasn't Hillary and it remains to be seen if they will support him against someone else. In any event, he really can't afford to lose very many supporters BUT, he can also gain supporters from those who may have been reluctant to support him in 2016 but become impressed with his performance.
One thing I think a lot of Democrats have overlooked are the "Trump Democrats." Many blue collar workers across the Midwest who traditionally have voted Democrat and, in fact, may have voted for Obama in 2008 and 2012. I believe this is what ultimately won the election for him. He connected with these people in a way the Democrats haven't found an answer for and don't seem to have a clue as to how they win back.
On to your question. I think Trump could probably pull it off better than anyone in recent memory. Especially if he were able to take a coalition of Senators and Representatives with him. If Trump were to team up with, say, the Freedom Caucus to create a New Conservative Party, they could pose a formidable challenge as a third party. Problem is, Trump has a tendency to use the Freedom Caucus as his whipping boys when things don't go his way. He has simply chosen to show more loyalty to the Establishment side who are controlling the agenda. Now, maybe that's a numbers thing, Trump isn't particularly "political" in terms of ideology. So for all the reasons I think it could happen, there are just as many reasons for me to believe it won't happen.
I think what we need to look at are the 2018 midterms and what transpires there. If the Establishment suffers a backlash, which I think is highly likely, then you will probably see many Establishment types moving more inline with Trump between 2018 and 2020. While Conservatives often find themselves on the other side of legislative initiatives (like repealing ACA) it's not really Trump they are opposing as much as the Establishment. Trump, for all intents and purposes, has been extremely satisfactory in pushing a Conservative agenda. Conservatives have gotten far more from him than they would have with a Jeb Bush or Marco Rubio.
