Yeah, pretty much. Except there's a bit more to the complexity. Allow me to re-write your over simplified description: "No matter how bad X is, I will vote for X because X will appoint one, perhaps two SCOTUS positions that align with my values and Y is worse and will appoint one, perhaps two SCOTUS positions that completely go against my values."
I don't care how bad management is, I would rather this company fail than go in a direction that I don't like.
Because you can go to another company. Its a little different when it is your country. But going back to your company example, sometimes your company goes in a direction you don't agree with or like. That doesn't mean you hope the place burns to the ground. That is a highly egotistical (my way or nothing) and arrogant philosophy to take. Although that seems to be the left's philosophy exactly these days. It was the right's philosophy under Obama. And it was wrong, then.
All the democrats had to do is come up with a fairly youthful moderate with a little charisma (who wasn't gay) and this thing would have been a cakewalk. I don't see a path at this point to end the nightmare unless by some miracle Biden makes it to the end and chooses well for VP.
I said with charisma, Beto isn't that likeable and he is a terrible speaker. I know it's a pipe dream to get a candidate who could excite and speak like Obama, but something closer than what we got would be good. I know it shouldn't matter, but it does. Trump keeps his base because he talks like them, reasons like them. those hillbilly fuckers at his rallies wouldn't know a policy other than 'keep the fucking Mexicans oTt and don't take my AR 15' if it hit them upside the head. The democrats don't have to be so radical. Like medicare for all, I am absolutely for it, but don't do it all at once and force people off their plans, that scares people. Do a public option that is better and cheaper than the for profit insurance companies, employers always looking to cut costs will see the savings and you end up at the same place over a longer period of time.
Buttigieg exceeds all but one of your criteria. Republicans won't vote for a Democrat anyway in this political climate. True Democrats and Independents shouldn't give a damn about orientation. That should (theoretically) be enough. And how cool would it be for Republicans to have a gay president? After they gave Americans an odious president like Trump, it's time they got a little woke.
