There's a lot of talk about the possibility that Brown will become the 41st Republican senator, the lawmaker who can stop the Democrats' national health care plan. That's important, but here in Massachusetts, it's perhaps more important that Brown is seen as the solution to the problem of too much one-party government. As the Brown team sees it, the political situation in Massachusetts, dominated by the Democratic party and increasingly marked by corruption (three consecutive state Speakers of the House have been indicted and forced to resign in disgrace) is making state voters wary about the one-party domination of Washington, where Democratic leaders are rushing toward new extremes of federal spending and government intrusion. "I think I represent a breath of fresh air, where people know that I'm going to go down to Washington to be a check and balance," Brown says.When Brown talks about what he's up against, he says it very simply: "It's me against the machine." By that, he means the Massachusetts machine -- the Democratic party, the patronage, the entrenched network -- as well as the national machine that has targeted him since word got out that he might win. "It's revving up," Brown tells reporters at Zoll. "They have MoveOn.org, SEIU just took out a major buy, potentially the president is coming this weekend." Brown has his own weapons -- talk radio and conservative Web activists have been huge helps -- but in Massachusetts at least, he's still outgunned.
