Why not McCain?

George Will opines about John McCain and provides some perspective for the "wide open" Republican primary race ("Waiting for Straight Talk"). I'm not sure that he can be accused of not "talking straight" for espousing his all-over-the-map political views (historically and even in the present). I think he's just being himself--a career politician with a seemingly undisciplined mind, respected by almost all Americans for his pre-political biography and beloved of the MSM for his propensity to make mischief in the opposing political party.
