A Massachusetts earthquake?

Guess we won't start to see returns for a while, but almost all the cable predictors suspect a Scott Brown -- Republican! -- victory in the Massachusetts Senate special election today. It would be an amazing political turnaround. Mass. last voted for a Republican senator (Ed Brooke) in 1972. This Register editorial explored some of the reasons and the possible implications, first for ObamaCare and for the rest of his agenda. It is becoming more and more clear that Obama (as Bush did in 2000; his ratings were starting to plummet before 9/11) overestimated his mandate and has alienated a larger proportion of the country than he ever imagined was possible. I suspect he still doesn't comprehend the breadth of his growing unpopularity.
