So not quite the same animal we are dealing with now.

But all things being equal, we can hope.

but I'd be surprised if he had nothing to do with the deal with the Iranians to hold the hostages, which pretty much threw the election to St Raygun.

Bush is as corrupt as MF45, he's just not blatant or an imbecile

He didn't actually win amongst the populace in 2016, with Russian help. He skated with the EC. 40k votes the other & nothing.
People bought the "business man" nonsense and now that we're headed to recession & 401k values are zero growth, the "good for the economy & my 401k" thing has evaporated.

...the Omnibus Budget Reconciliation Act of 1990.

Conservative media then proceeded to perpetually crucify him for having gone back on his "Read my lips, No New Taxes" pledge. They continued grumboling about it even through election season, though by that time their main focus was finding every way possible to smear Bill Clinton (and inventing new ways when that wasn't enough).

Not disagreeing with you, just noting that the conservative messaging and propaganda environment back then was a drag on Bush in a way that it won't be for Trump.

It might end up being a drag on him in a different way (like the lighting-fast, Soviet-grade apparatchik flips when the Republicanly Correct position suddenly changes), but not the same way.

But, he did a phenomenal job of explaining why the tax increase was needed. The bleating brought us Perot but even absent that, he got creamed.
The sliding economy doomed him, no matter what far right pundits said or did. They sure didn't prefer Clinton. So, they bloviated, then voted for Bush.
He lost anyway.

Poppy Bush was never liked by conservatives the way they loved Reagan. Trump seems to be far more popular with Republicans as well. In 1992, I'm sure at least a few voted for Perot. This year, I think 3rd Parties will be exceptionally weak.
