Trump is fading, like Sen. McCarthy in the 50s (who took to the bottle and died soon after). He was entertaining to some in '16, but now has the tired refrain of a sore loser. As you said, he can't supply his fervent followers with enough fresh red meat. Increasingly, it also seems that any smart, methodical person left the sinking Trump ship long ago, and the remaining QAnon (full apocalyptic deep-state accounting in '20…no '24…no '28) and Proud Boy dregs are incapable of leading any kind of Revolution...the attention spans don't last long enough! Trump's best hope are the unqualified judges he appointed and corrupt legislators in a few Red States.
