here's what really happened in massachusetts
in spite of tales of traffic jams outside polling stations, the turnout was far smaller than in 2008.
the big winner that year was john kerry, who outpolled obama as well as brown:
22%, or 23% of dems voted for brown. that's bad news for the theory that the greater number of independents decided the race, because even the lowest estimate of dem crossovers more than accounts for brown's 5% winning margin, if they turned out in the same proportion as the independents. if not, the stay-at-homes decided it.
