Vote for people with a track record that fits with your own thinking. Green party candidate would be my choice.
Coming from a country with the exact same political system (two-party, imposed by the US obviously), voting for the supposedly "lefty" party, does absolutely nothing for the farewell of the people.
Since democracy returned to my country in 1990, the "democrats" equivalent party has been in power most of the time (including the socialist party in that group), and it's been the same as in the USA. Only nice words to get the votes, but when in power, they go against the people and ended up privatizing the whole country. Education, health system, pensions, etc. Plus, all the typical things like saving the big corporations and sending corrupt politicians and businessmen to ethic classes, instead of jail.
It's a fake democracy system, imposed by the economical elites, to make sure, no matter who wins, they win.
For the last elections, a third party came in strong (a true left wing party, imagine something like Bernie Sanders, AOC) but they fell short and eventually, the right wing party ended up in power.
One would think, ohh, so stupid!! hahah why vote for a party with no chances!!?? now you let the right wing to win again. Happy now? (That's the typical thing you read here)
Well, actually, yeah, it ended up very well. The right wingers thought they could keep exploiting the people, but surprise, a huge social awakening happened, and the right wing government has been absolutely unable to complete with any of their original plans. (The same would have happened if the fake "left" would have won)
And the political panorama seems to be going to change for ever, and for good.
So yeah. Any US citizen who wants change in America, needs to vote for decent people with a track record, not for parties who talk nice.
Even if that means a new Trump government. The people will not take it any more Trump or Biden craziness, and will take the streets before letting the elites to keep abusing them.
Almost 50% of the voters in US don't even show up to vote because they know it's the same shit if red or blue wins. (and subconsciously, they think voting third party would be a waste of time because of people like in this thread that keep repeating that)
You can't even script it. 90% of democrats, probably big majority of independents, and also a small but decent chunk of republicans support Medicare for All, but not even a whiff about it from Biden or his team. Their bosses won't allow it.
