Re: Except ...
Nixon was more or less the definition of the Republican Party (for his day- it’s changed somewhat since then).
Bush1 and Bush2 also pretty closely aligned with “the party”.
Now Reagan...you are aware that, like Trump, he was a Democrat most of his life? And, like Trump, his policies were pretty drastically different than what EITHER party had been doing up to that point. Reagan and Trump both kind of just did their own thing.
What Reagan did have going for him is that, AFTER implementing new policies, he became popular enough that the Republican Party was sort of dragged kicking and screaming into adopting many of them. But the party leaders certainly didn’t LIKE Reagan’s politics.
Time will tell if Trump plays out the same way or not.
