Go McMullin. Ain't nothing wrong with going to 'coffee shop to coffee shop' gathering up votes.
But McMullin's not going coffee shop to coffee shop. Because that was arguably the worst part of this whole thing. Because, in addition to being insulting, it was tone-deaf (arguably worse in politics). Because Trump seems not to know that you can't have coffee in Mormonism.
Next thing you know, Trump will start complaining about the big challenges of alcoholism and heroine abuse in the Mormon community. It's bound to happen some day. He'll probably invite a dozen of Mormon leaders for a discussion over high tea in his Trump Tower condominium.
