That's frustratingly undeniable.
But also, there's a Millenarianism to the MAGA movement that's costing them support over time. The pool of Trumpies is shrinking as the milquetoast Lindsey Graham neocons and the faux-libertarian Tucker Carlson fascists bail out of Trump's party. Same shit happened under Bush, at the tail end of '07/'08. You had a bunch of Radical Centrists and Professional Conservative Contrarians with their fingers to the wind, saying "Um akutly I like this Obama guy because he's popular and Shrub isn't".
The people who are still pro-Trump are crazier because the sane cyncial people who were just along for the ride during the "good" times are leaving. FFS, Karl Rove says he's voting Democrat this year. That's how thin the base is getting.
