Not sure why you're getting down voted so much. We have no truly leftist or left of center parties in this country. We have fascism-lite and status quo right.
When Nixon won he won by a super large percentage. Almost all the states were red. Look at the electoral map for Nixon's win, if you can find it, it's shocking. You know why it looked like that? The DNC ran a progressive candidate. And they've not done that again since.
Not saying Dems aren't better, by far they are, but they aren't progressive and we can't expect them to enact progressive changes.
Just gotta keep voting for the lesser of the evils until these dinosaurs either retire from, or die in, office. It's sad, it's frustrating, but it is all we can do for now. Keep voting for the party not actively rooting for a dictatorship and we might make it through this.
