If the Democratic Party takes as leftward a turn as the Republican Party has taken rightward, I'm out, and that's what it sounds like many are advocating in this thread. I don't see leaning into the culture wars from a leftward perspective as easing the rancor in any way. I see it having the opposite effect.
I kinda like the centrist D party of the 90s. It was actually probably the best governance of my lifetime at the federal level.
It's ok, I am perfectly fine being politically homeless and not supporting either party until I see some people who are both moderate and effective at the helm of one or the other. There is certainly no moderation in the Republican Party, and there is no effectual strategy within the Democratic Party, so...
But hey, I can be won back by either side. That's the beauty of being a centrist. I really don't give a shit if you have an R or a D by your name. Convince me you are part of the solution vs part of the problem and you can have my vote. Or don't, and you'll have to find somewhere else to get my +1.
