Alexander Hamilton. He would be the first president born outside the United States, the first president who'd be ineligible if he was born after Independence Day(neither of his parents were American, so he'd get in via grandfather clause), the first president born out of wedlock(only Bill Clinton has even been half-seriously rumored with that and John C Fremont is the only nominee known to be a literal bastard), 1st US Secretary of the Treasury to become president. If the Reynolds affair doesn't ruin him he'd be the first president who's confirmed to have cheated on their spouse(Garfield takes that spot due as its known he confessed about it to his wife), play his cards right and he might be the first to become president in his forties(beating James K Polk for that). And if the speculation of him and John Laurens is any indicator, he might be the first president speculated to be LGBT(beating Buchanan to the punch, though there's a lot more evidence for him)
Was there any non-white, non-Christian, LGBT woman before Barack Obama who was in any way considered for a major party? I want to see how many minority tropes we could get in one person with that
