I'm pretty predictable on the subject: Local elections turn on local personalities and parochial factors and should not be hyped by the media into some sort of national trend.
Except for this one.
The Massachusetts Senate race is different because Martha Coakley should have won it without breaking a sweat. For all her flaws as a candidate--who takes a week's vacation in a five-week race?--it shouldn't have been close. And whatever Scott Brown's strengths as a candidate (other than once being Cosmo's "sexiest man"), he was clearly boosted by growing resentment of Obamacare and the nation's direction in the bluest of blue states.
