A bti of evidence on how Bush’s speech worked.My trainer is 40, black, from the islands, and generally apolitical. Weeks, months go by without us mentioning a politician. He watched Bush’s speech Monday night, though, and gave him an A. Partly for presentation: he said Bush looked right into the camera and didn’t give any “goofy looks.” Partly for substance: the speech struck him as coherent and even-handed.On the one hand, this is no benefit to Bush, or to the GOP, whatever ensues, since I don’t believe my trainer votes, and if he did, I can’t imagine him voting for Republicans. On the other hand, it does show that we who live and breathe these matters often misunderestimate how the rest of us react.
