A vote for Biden if you live in a toss up state is saying: "One more chance to fix shit," and then actually doing the hard work to do so, like tearing up the oligarchical two party system, which has to be done bottom up. It will never happen top down.
A vote for Trump, which a non vote is, is saying, "Fuck it. I quit." And watching the end game on women's rights, LGBTQ+ rights, and minority rights (what Trump's and McConnell's SCOTUS haven't already stripped away -they've promised to go after the rest of the Voting Rights Act).
American presidents are always centrist. It's the only way to win presidential elections.
The fix to that problem is building a better bench at the legislative level. Progressives are winning more and more elections lately each go round.
The only hope is making sure that the guy who moved the American embassy to Jerusalem from Tel Aviv and openly cheered Netanyahu on when he was president doesn't return to office to finish the job.
I'm a follower of history. I fully understand what a second Trump term means, and I believe you do, too.
