I'm voting for Biden unless there's another nominee that will be the predominant choice against Trump. I don't like either of them but the choice is easy. Biden can't win my state, but I'm still going to vote for him literally just because he is running against Trump. I might cow about how I ate the Dems won't run on much else, but the contrast is big this time. It's always been really though, the Dems should be our new right wing party and a new farther left party like the Green party ought to be the more leftist faction. Dems to me already are neolibs with a neocon leaning. Leftist Populism must be embraced by the neolibs long term. Either way something has to give. Too much wealth to go around (even globally). The greedy old ideologies of constant growth at the expense of the poorest people in the world can't go forever. Growth economics can't go forever either. I have hope. Just go vote because that's what we can do easily as a minimum effort.
The neoliberals won't embrace anything unless there's profit in it.
Preferential voting is the only chance of a progressive gaining the power they need to make desperately overdue changes to healthcare, worker rights, housing, cost of living, etc.
A neoliberal government that occasionally panders to progressives is better than a neoliberal government that gets horny at the idea of spitting in poor peoples faces, which is better than fascists.
But we need to do so much more than "not making things worse".
