I'd gladly vote for a progressive if given the option to in the primaries, but should they not win, the solution to the problem is not letting the country get even worse by letting fascists into the White House during the general election.
I'm not a Democrat and would gladly vote for a democratic socialist candidate if I could, but pragmatism is necessary to keep fascists from running the country. So much suffering could have been prevented had people been useful idiots to the Republicans by elevating them with a false moral equivalence.
And anyone who didn't vote for Harris over Palestine has now not only doomed the Palestinians, but Ukrainians fighting for their sovereignty, hardworking immigrants, and transgender, low-income, and minority Americans as well.
Impeachments mean nothing without a conviction.
