This is a doozy of a post, and not unconvincing:
The easy analysis of what is happening is to say that “even in deep-blue Massachusetts people are rejecting Obama’s agenda,” but none of this makes any sense. I don’t say this because I have any sympathy for Obama’s domestic agenda, but because I don’t think there is any way to understand this response by voters in a heavily Democratic state except as an expression of pure anti-incumbency sentiment and a desire simply to shake things up. After years of mocking Obama’s signature campaign slogans, Republicans have found that their best path back to power is exploiting the desire to change for change’s sake.
Assuming that Brown will win today, the lesson has to be that no winning party should ever attempt to deliver on its promises, and under no circumstances should it follow through and actually deliver promised legislation. I say this as someone who would be happy to see the current health care legislation fail.
