I wrote a WoT, but had to strip it down to this.

Republicans have been offered everything. They obstinately and willfully reject any overtures or policy that could aid them. Reductionist, low-effort logic combining ideological and religious identity that offers the perception of control over their lives and yet the strings are pulled by the wealthy.

We can offer the common Republican everything, even control, and they will take it and set their opponents on fire with it. Just like they’re doing now. The only hope is to cut the head(s) off the snake. Otherwise they’ll just continue throwing good money after bad. They’re too invested to change.
