Are most of Trump's supporters continuing to hang on because Trump is still the best chance for winning in 2020?

of course..........they are clinging to the railings of the sinking TRUMP-TANIC. because they still perceive the "solid ship" under their feet, the far better bet, than those rickety. little lifeboats..........despite the bow already being under water.

They don't want to BELIEVE yet, that the ship has been mortally wounded, and it will *somehow* still manage to float and get them to the next election , at least.

The band in the Senate is still playing, so there can't be any REAL danger, right?

(Keeping in mind, all the band members drowned or froze to Death in the water. )

Let me make this clear to you. Trump did not win the last election.  The democratic party lost it. If there wasn't so much in fighting they would have won by a land slide. The division has gotten worse since last election. 

We support him because he's doing a good job for this country and the Democrats have been doing this witch hunt for 3 years.

Mike Putz knows full well that he could never become POTUS on his own. This is a guy that can't even be in a room alone with a woman without his wife being present. Maybe he's afraid of his throbbing biological urges coming into play. So he's a potential rapist, or he's completely puzzy-whipped.

Pence is hoping for an impeachment/removal of Trump. He's gotta ride the Trumpian coattails. He knows full well that he'd be trounced thoroughly by ANY Democrat candidate in an actual election. If Pence had that 2x4 surgically removed from his a**, he'd end up flat as a pizza.

And I have my doubts as to whether he could "rouse" his own wife. Women don't like bootlickers or toadies.

Most Trump supporters do so because he embodies what many of them want: to tell everyone eff off with impunity. This is a big problem in the US these days. People seem to be incapable of civil discourse.

Lol I do not wish for Trump to be elected but he is more than just their best chance. He will win.

No, it's because Trump was right about one thing: he could commit murder in public and not lose a vote. On that day, Trump was one-third of the way to doing better  than a broken clock.

I will support the president that I voted for. Despite the Liberals attempts to smear his name with phony hoaxes.
