A lot of Democrats assume they’ll be able to take back Scott Brown’s Senate seat (No! It’s the people’s seat!) when he comes up for re-election in 2012.

But take a look at the list of likely challengers Boston Phoenix political columnist David Bernstein has come up with. Marty Meehan? Vicki Kennedy? Frankly, if Brown can find a way to establish himself as a moderate, Massachusetts-style Republican while not alienating the national party leadership, he could be in for a long run.

The only significant new talent to emerge on the Democratic side in Massachusetts in the past 20 years is Gov. Deval Patrick. He’s had a rough time in office. But if he can somehow win re-election, he might be the best of the Democratic contenders against Brown.
