Conventional wisdom among Democrats since the Clinton administration has been: “if you triangulate yourself to be one iota to the left of the opposition, every center-right moderate republican will vote democrat. And everyone left of them has to vote democrat anyway, so you’ll win a majority as long as you’re right of the majority. If you lose, it’s because you didn’t go far enough to the right.”
This doesn’t actually work, since fascists just vote for the real thing over diet-fascism, and democrats passing right-wing policy decreases their turnout, but pretending it does allows them to justify policies that don’t conflict with their donor’s interests.
