Too much arrogance and inner conflict. Liberals always really hate everything, their inner life is a mess.
"If the investigation of Arpaio’s civil rights abuses was motivated by the Sheriff’s embrace of birtherism, how did the feds manage to start first?"
Notice how any form of the word "alleged" is conspicuously absent from that statement? That the sheriff is guilty of "civil rights abuses" is a foregone conclusion, based on the wording. No conservative giving Sheriff Arpaio even a shred of a benefit of any doubt would word that statement, that way. If I were a kitten, I'd give the Blade a sniff or two.
