Rep. Michael Capuano (D-Mass.) said over the weekend that he'll decide in the next few months whether to run for Senate in 2012.

Capuano, who unsuccessfully sought the Democratic Senate nomination in last January's special election to succeed the late Sen. Edward Kennedy (D), said he's being encouraged to run.

"I'm considering it," Capuano told WCVB television in Boston. "I'll make up my mind in the next few months as to whether it's something that I want to do, that my family wants to do, and whether it can be done."

Capuano is among several Democrats considering a run to unseat a top target of the party in 2012: Sen. Scott Brown (R-Mass.).

Brown won last January's special election in an upset victory, and has since then sought to build a campaign war chest and stake out a centrist position going into what's expected to be a difficult 2012 reelection effort.

The GOP senator's upcoming filing with the Federal Election Commission is expected to show him with a whopping $7.1 million in cash on hand, the Boston Globe reported on Monday. That kind of piggy bank, which is sure to be bolstered by aggressive fundraising over the next two years, could prove a firewall in the Republican's reelection effort in normally-Democratic Massachusetts.

"I've never raised more money than my opponent, in any race I've ever had. I will not have more money than any people who are looking at this race, but I'll have enough money," Capuano said of the race, referring to both Brown and his potential primary challengers.

Capuano said Brown had made both good and bad votes as senator, but the Democrat honed in against the senator's vote to extend expiring tax cuts for two years as one of his worst — a possible preview of a 2012 campaign theme.
