I think you're mostly just looking at things solely at the lens over overturning the Reagan consensus and ignore every single other thing.
What you call the "Reagan consensus" has absolutely nothing to do with what's currently happening now. To what all the "Reagan consensus" amounted, was southern and conservative Democrats caucusing with Republicans for two reasons: one, they agreed with Republican policy, and two, Republicans had control over the pork faucet. That ideology (and inexhaustible thirst for pork) was there a long time before Reagan, and it's still there albeit more normalized than it has been. Look, I'll lay it clear from the perspective of a former party insider.
The contemporary party's fully back to its Gilded Age machine politics roots. Both Clintons spent twenty years rebuilding the old party apparatus and coalition-building between the Dixiecrat faction and liberal coastie PMC's, at the cost of throwing the Midwest and almost the entire rust belt to the wolves. Howard Dean's tenure as DNC chair was the New Deal coalition's/progressive Democrats' last gasp, and that culminated with the 2006 blue wave and Obama's nomination against the 21st Century's analog to Boss Tweed, Hillary Clinton.
Then it turned out Obama or any of his people couldn't administrate a party for shit (ironic for quasi-progressive technocrats), and they ran the party financially into the ground. The Clinton machine bailed the party out, and worked very hard since 2015 to consolidate power to entirely predictable results since. The machinery's different than it was in the 1800's, but the form and function are still the same. I mean if you want an outright bold-as-brass example of this political patronage in action, look no further than the PPP loan fraud by Democratic party insiders and influencers.
If anything, to what you refer as the Reagan consensus would be a significant step
leftwards to where it currently is. What you don't realize is the country's
already surrendered to the far right: the Democrats in charge of the party don't do shit, and won't stop Republicans, because
they support Republican policy. They just won't come outright and say it, and instead ratfuck challenges from the left while killing any progressive legislation before it sees the light of day while putting forth
just enough effort to merely appear as if they tried but failed.
All this shit you want to say Republicans will do if they win in 2024, has already been done over the past fifteen years. That's what I'm saying.
