There’s also nobody who might emerge out of the right who would bring something that will make life for everyone better. Only the Democrats have a chance of doing that and engineering a better system that might eventuallyundermine their own political hegemony. Would they without pressure? Of course not. But the right will never even be pressured to do anything like that intentionally by it’s base, almost by definition basically.
You can and should support them as they align with your values, but you’ll never get enough votes for them to have any chance of overthrowing the big two. It has to be changed from within, unless you’re prepared to try violence.
