There’s an interesting brouhaha developing in the Brown-Warren race.

Vicki Kennedy (widow of Ted) has teamed up with MSNBC and the Warren campaign to organize a debate in late September.

Scott Brown accepted the invitation on the conditions that MSNBC not be a sponsor and that Vicki Kennedy withold endorsing in the race.

Now Kennedy is saying she will not abide by that condition and may make an endorsement (gee, I wonder who she will endorse), via The Boston Herald:

Victoria Kennedy is refusing to sit out the Scott Brown-Elizabeth Warren race and withhold her endorsement, thus rejecting a debate demand from the Republican senator’s campaign, officials tell the Herald today.

Officials with the Edward M. Kennedy Institute sent a letter today saying Vicki Kennedy will not abide by Brown’s conditions.

“This non-endorsement pledge is unprecedented and is not being required of any other persons or entities. To us, such a pledge seems inappropriate when a non-media sponsor issues a debate invitation,” officials with the non-profit institute wrote. “We can assure both campaigns that the debate will be fair — just as the one we co-hosted between Senator Brown and Attorney General Coakley in was fair.”

On the surface, one would not think Brown would want to pick a fight with a Kennedy in Massachusetts.  On the other hand, his “this is not the Kennedy seat, this is the people’s seat” line worked quite well against Martha Coakley.

Havard Professor teams up with the Kennedys against Brown.  That could be a winning narrative for Brown.
