I suspect it will fall mostly on deaf ears.
I've been beating a similar drum for quite awhile. That distilling everything down to tribal identity associations is not great. Not for our party, not for the country. But it's so ideologically baked in - highly radical ideologues have a very firm grip on things - that I'm not sure how to undo it. But there are a lot of quarters of ideology we defend to the hilt that I often watch and think, "How do you think this is a good idea? No one outside of whatever bubble you're in thinks this way or wants this. People actively hate this shit, and they ain't all galloping right-wingers."
But, that's just shouting into the wind.
We should be absolutely cleaning up electorally. Nothing should be close in this country as the Republican party is busy so thoroughly imploding. And yet, we're not. And people point many fingers outward for why that is so. White supremacy. Half the country is a cult. The electoral college. There's just a complete inability to look inward and start asking a few questions.
Entities that cannot course correct do not weather well medium and long term. People hate Trump, but I think he's this kind of bizarre lifeline, a temporary reprieve from an electoral reckoning. As long as he's around and repulses enough people - and he does - we're sliding by on account.
That isn't going to last forever. I think 2028 is going to be some shit. It's already been starting over the past five or so years, but Trump has sucked all the oxygen out of our politics and commanded everyone's attention. Once he's gone, and people start examining more closely what our politics look like, I think there are going to be some questions where our answers are not going to be anything close to what people want to hear.
And, weirdly, everyone will be super surprised.
