i'm not from US - we've got a multiparty system that seems to kind of work - but I've done one of those political alignment tests for parties, got a result, and then proceeded to do a political alignment test for politicians. None of the folks I was supposedly aligned with were members of the party I was aligned with best. make of that what you will.
No, its full of corporatocrats [0]. Corporatism [1] is a political position (Wikipedia calls it an “ideology”, but it may be better to be viewed as a facet of ideology found in lots of very different ideologies; e.g., fascism includes corporatism as a component), but its not one that is particularly popular among Democrats, either in leadership or the base, neoliberal or progressive (though there definitely is a progressive corporatism that has some support.)
Anecdotal.
There are tens of millions of GOP voters, I have many friends that support GOP, non of them is a fasict.
