Stuart Rothenberg tells us:

Democratic desperation and other compelling evidence strongly suggest that Democrats may well lose the late Senator Edward Kennedy’s Senate seat in Tuesday’s special election. Because of this, we are moving our rating of the race from Narrow Advantage for the Incumbent Party to Toss-Up.

The Democrats, belatedly wise to the very real chance they’ll lose what should have been a slam-dunk seat for them, are flooding the airwaves with negative ads. (Creigh Deeds did the same thing in Virginia, which only served to confirm that he had no message of his own.) Rothenberg is skeptical that this will work:

Late Democratic efforts to demonize Republican Scott Brown, to make the race into a partisan battle and to use the Kennedy name to drive Democratic voters to the polls could still work. But the advertising clutter in the race works against them, and voters often tune out late messages, which can seem desperate.

What several weeks ago seemed like a conservative pipe dream — a Republican win in Massachusetts — is now a real possibility. And if it should come about, prepare for a tsunami to hit Washington D.C. The realization will surely sink in for each incumbent Democrat: if the Massachusetts’ Senate seat isn’t safe, then neither is theirs. And those who want to vote for ObamaCare and the rest of the Left-leaning agenda had better consider the political consequences.
