I don't think it's been scheduled yet, but I believe there will be a special election for Rep. Richard Ross's (R) seat now that he's been elected to the State Senate.
Massachusetts' Ninth Norfolk district is indeed a rare breed: It's a McCain district.
* McCain 10,830 (49.18%)
* Obama 10,794 (49.02%)
* Other 397 (1.80%)
I presume the front runner for the seat is Norfolk Town Moderator Dan Winslow. He also served as Chief Legal Council for Governor Mitt Romney.
The domino effect from Scott Brown's win pushing into summer special elections is amusing, even if it's not uncommon.
I am sure the MA GOP also enjoys hearing the words "Safe Republican" to describe both a state senate seat and a State Rep seat. Probably a rare occurance for an open seat since most are Safe Democratic or beyond.
Enjoy it while you can (this is still Massachusetts
)
