In what sense was Trump’s speech a “well-reasoned argument”? It was certainly a well-imagined wish-list, in that it spoke approvingly of a lot of things that most people would agree are good things to have.
But it presented absolutely zilch in the way of persuasive argument that anything Trump intends to do is actually likely to produce any of those good things.

About 70% of the things mentioned in Trump’s speech tonight were things that ought to in theory be bipartisan, but it was or will get ad-hominemed because Trump is Trump.

Nah, it’s not that people are going to disparage any genuinely good ideas merely because they don’t like Trump. It’s that people are well aware that using vague feel-good rhetoric to disguise a severe lack of actual genuinely good ideas is Trump’s standard operating procedure. So why should we believe that Trump’s vague feel-good rhetoric is a harbinger of any actual genuinely good ideas this time?

Let’s pretend for a moment that it wasn’t Trump, but rather, President Evan McMullin or someone like that, saying the exact words. Wouldn’t it get pretty broad applause?

If McMullin didn’t already have a well-earned reputation as a cynical, unscrupulous, untruthful, ignorant con artist, then sure it would. It’s not about disliking the content of the vague feel-good rhetoric, it’s about the distrusting the integrity of the politician spouting it.
Why are you imagining that because Donald Trump can recite an optimistic speech off a TelePrompTer, he’s suddenly become a different person from the under-informed, spiteful dictatorial narcissist we see on his Twitter account and in his interviews?

The very definition of ad hominem is to oppose something on the basis of the speaker, not the message/content […] but to oppose it “because it’s Trump” is the very definition of ad hominem.

Like many other people, you misunderstand “the very definition of ad hominem”. [ETA: as TonySinclair has already pointed out.] An ad hominem argument is logically invalid as a rebuttal of the substance of a claim being made. But it is not invalid as a critique of the competence or trustworthiness of the claimant.
E.g., if Trump says “The general Birch and Swinnerton-Dyer conjecture in algebraic number theory is true”, and I respond “It’s probably not, because Trump is a chuckleheaded dishonest shitgibbon”, that would be an ad hominem fallacy. Trump’s personal characteristics have no bearing on whether this mathematical statement is actually true.
But if what I respond instead is “Irrespective of the truth status of the Birch and Swinnerton-Dyer conjecture, Trump is incapable of understanding it and would have no scruples about lying about it”, that’s not an ad hominem fallacy. It’s a critique of Trump’s reliability as a claimant rather than an attack on the veracity of the claim.
I would not believe that Trump was a competent research-level mathematician just because he uttered some words about the Birch and Swinnerton-Dyer conjecture, and I do not believe that Trump is a competent or trustworthy politician just because he uttered some words about making Americans happy and prosperous. In both cases, there is far too much available evidence about the sort of person Trump really is to take his words at face value.
