FWIW. Ideology could be either way based on that info. People sometimes register for the opposing party as a tactic to vote in the primaries for the weaker candidate (less likely to win). Donating to dems could either mean allegiance to dems or it could just as well be a true conservative who hates Trump (because true conservatives tend to oppose Trump as well over Trump’s disregard for antitrust situations and his sloppy spending). A Trump-hating republican would also likely register as republican to vote against Trump in the primaries.
