“We Need To Build Three Walls. Mexico, Canada, and…the, uh, What’s the Third One There?”

I’ve been resistant to the idea that Scott Walker was the Rick Perry of 2016. And I suppose it’s nearly impossible to be that bad, and with Jeb!’s campaign leaking at least as furiously I wouldn’t even say he can’t win the nomination. But it’s becoming increasingly hard to deny the wisdom in djw’s analysis. The desperate attempt to out-Trump Trump by appealing to the non-existent Republican constituency terrified by Canadian immigrants would seem to be pretty clear evidence that he has no particular idea what he’s doing.

…Roy is also off the bus:

I've predicted Walker to win because his dumb-as-you act is so cynically great, but cripes, maybe he really is dumb https://t.co/ATXszRq0Oc

…some very smart thoughts about Walker’s parochialism problem, which Dana also raises in comments.
