I usually abhor psychologizing by amateurs like myself but it hit me just now that there’s a kind of timidity in Walker’s constitutional* refusal to negotiate.
I think he’s afraid he’s not smart enough to handle himself in a serious policy discussion.
I think he’s a political idiot savant, but when comes to policy, he’s quickly out of his depth, and at some level he knows it.
So he just takes a position and sticks to it, even if he has to resort to lies — perhaps even to himself — to justify it.
* Not in the sense of rules of governance, but in the way his personality is constituted.
