well, we are have and are continuing to witness the Republicans ceding power to someone who has no core values, let alone core values that align with their stated historical views. Everyone fell in line just fine after Trump gained the nom. Either they were being disingenuous all along, which I do not believe, or they would rather look past all of the downsides to stay in power. Why do you think the Democrats would be any different in this regard? Every one of them will fall in line if Bernie wins the nom because it's better than the alternative. Will it be enough? Who knows, but Democrats aren't going to boycott this election under any circumstance.
