If Trump ran as a Democrat but had the exact same campaign, he'd never win the nomination, so it's a moot scenario. Actually I should ask who should I vote for if not Hillary? The implication seems to be I shouldn't because I don't think she'd be that great of a President, but that's not really the point to me. Because if Hillary simply implements generic Democrat policies and basically functions as Obama's third term (and I don't see any indication otherwise), then that's perfectly fine to me, and it goes without saying about how that is in comparison to a Trump presidency. That's the reason for my "hackery", not just blind party loyalty. I've said before that Hillary wouldn't even make my top 25 list of people I'd want to be President, even if just limited to political figures with a large enough profile to run, but being a crybaby and refusing to vote for her when she'd be at worst something like 75% as good as Obama especially in comparison to Trump is a pretty mind-bogglingly illogical action.
As far as her 2008 campaign goes, blaming her for the actions of her dumbest supporters is no more logical than blaming Sanders for those infamously idiot "Bernie Bro" Reddit supporters of his, and there's no reason to believe she supported any Birther or "Obama is a Muslim" rumors especially since those obviously did not help her in the Democratic primary. She did surround herself with some pretty odious (and in hindsight, hilariously incompetent) people like Mark Penn and Harold Ickes, but she's stayed far away from this time. I'm convinced that Hillary in 2008 was at worse a tragic villain, someone who probably had good intentions in her pursuit of power (I mostly certainly believe Hillary believed she was the most qualified person to be President in 2008 after all) and made some questionable moral decisions, but holy sh!t, how on Earth does that make her any worse than me? I'm reminded of a FANTASTIC Barney Frank quote from 2004, when he was asked how he could support John Kerry (during the primary) despite Kerry's then opposition to gay marriage. He replied "I've only voted for a perfect person once in my life. Once I ran for re-election, I wasn't perfect anymore."
But beyond all that, Obama has obviously forgiven her and the black community has, so some white person still holding it against her is almost kind of condescending. And judging her by her record after that, I don't see any issues. After all she was a fantastic Secretary of State, and seeing as how the people who tend to condemn her tenure as that as "too hawkish" tend to be the "RIP Gaddaffi
FF" types it's pretty clear why I don't take them seriously. Before his Senate career Obama had ties to the Daley machine and to the extremely odious slumlord and felon Tony Rezko, but none of that had any bearing on how he did as President and was a pointless thing to judge 2008 Obama on. And I think it's pretty obvious Hillary is not going to reveal herself as a closeted white supremacist after taking office, making her 2008 campaign completely moot today.
But ultimately the main reason why I wouldn't vote for anyone else is because from a point of pure rationality, there is no harm to me. Voting for Hillary, even if I didn't particularly like her (let's imagine this is 2008 and she won the nomination and I had plenty of bile toward her, but obviously would've voted for her over McCain in November) causes no harm to me whatsoever. So if she's the most tolerable candidate who has a chance of winning, for what reason do I have to note vote for her? I seriously can't think of any reason following basic rules of logic.
