A Republican strategist said something interesting and revealing on Friday, though it largely escaped attention in the howling gusts of punditry over Mitt Romney's birth certificate crack and a potential convention-altering hurricane. The subject was a Ron Brownstein story outlining the demographic hit rates each party requires to win in November. To squeak out a majority, Mitt Romney probably needs to win at least 61 percent of the white vote -- a figure exceeding what George H.W. Bush commanded over Michael Dukakis in 1988. The Republican strategist told Brownstein, "This is the last time anyone will try to do this" -- "this" being a near total reliance on white votes to win a presidential election.
