In the postelection afterglow, Republicans in the state repeatedly said, “We’re all Scott Brown Republicans now.” Several political insiders acknowledged that they are unsure of what that means.

“We’re in a state where the legislature is dominated by Democrats. To be a Republican is to be an independent here. That’s how I think of it,” said Matt Sisk, a member of the Massachusetts Republican State Committee…

His political career began in Wrentham, where he ran for assessor and kept moving up, winning his ninth consecutive election Tuesday. He will finish Kennedy’s term and have to seek reelection in 2012.

“Some politicians like the policy; others like to campaign. Scott Brown loves to campaign,” noted a Republican official who asked not to be named.
