This is more IMHO than a studied analysis, so please understand.
The last time the main Republican presidential candidate ran on issues of government was either Romney or McCain. During that same time, Republican legislatures rarely were for anything, just against anything that Democrats put forward.
They painted themselves into a hole where they threw away anything they said they were about (low spending, balanced budgets, free markets, etc) to fighting a war of negation. And it was slowly costing them. Thus they tied themselves ever more tightly to their single issues: abortion, guns, Christian identity.
And then they had a scare. The Tea Party, which for all it’s MANY flaws, started trying to hold them to some of those earlier budgetary demands, and threatened to split their minority control. But they weathered the storm, and when the Tea Party couldn’t accomplish anything, they faded into insignificance.
Then came Trump, and for the first time in decades, he invigorated the base beyond those seeking tax cuts and/or the wedge issues. He got people worked up, they cared, and more importantly they voted! Sure, they hate him, or wish they could be him / wield his base, but they saw a path to maintaining power.
Which means they have to keep their base riled up, angry, blind, and hateful. They focus on culture wars so they don’t have to accomplish anything other than owning the libs. And it works! Better yet, they can use the wave of popular support, especially in their strongholds to dismantle (more than they had already) democratic protections ensuring they will never have to surrender power.
And if anything is bad, they’ll continue to blame it on “the libs” even though they have literally purged (a la Tennessee) any impediment to their rule.
So, yeah, even if Trump chokes to death on a cheeseburger tomorrow, they’ll ride his martyrdom (he wouldn’t have been binging if they hadn’t unfairly, illegally indicted him) into perpetual control. He will always be there, and I fully expect certain battier Xtian communities to canonize him as a saint.
It’s bad folks, and getting worse. I used to see the nation moving past this, but as I said in an earlier thread, I now feel electing Biden was like getting the boy to put his finger in the dike - it’s paused the destruction, but the root cause is just as dangerous.
And even if we don’t get Trump in 2024 (for any of a number reasons), it is only a matter of time until the next Republican of the Fascist/Autocratic bent gets into power, as all the normal ones have been purged as RINOs. And they’ve proven that ignoring democracy, ignoring the rules, ignoring the facts, and ignoring the laws is a working option.
The next will be far, Far worse, whether it be DeSantis or someone else.
IMHO the best we can hope for is if Fox is destroyed or splintered by a massive loss to Dominion, is that the unified messaging for the Republicans fails as well, and they split into, say, a Xtian Nationalist, a Populist, and a Tea party Esque party. But I don’t consider it likely.
