I almost feel bad for Mitt Romney. He's obviously a smart guy, and when he was governor of Massachusetts he was pretty much the technocratic kind of governor the voters expected -- not pushing conservative social issues too far, creating a health-care reform that's a lot like what the Obama plan ended up looking like. But since he wants to be president, he has to get past a Republican primary electorate that really doesn't care about smarts and technocratic skill. Identity politics is king in the GOP, and Mitt just doesn't have an identity he can hang his hat on....
