you’ve gotta go left so hard that the current dems would split into right and left.

That’s great in theory, but if we do that, we’re giving the government to the GOP in the interim, and they’ve made it quite clear that if they get power, they don’t intend to give it up again. Not to mention, the effects of this would extend well beyond our borders. I’ve advocated very strongly for exactly this sort of action in the past, but now is simply not the time.
