Liberals are going to have to decisively defeat the modern conservative movement in a big election if they want to move past this partisan fighting. As long as each side is roughly equal in numbers, and the races are close, this will remain a pitched battle.
Let's hope this will be a big decisive progressive win in November. But --- let's not count on it. I think the smart money is on a close election, which means there is no margin being nice to Republicans
There's no viable "post-partisanship" position toward the Republican party as it currently exists.
