BROWNOUT…. Sen. Scott Brown (R-Mass.) apparently has a viable plan to stay a Republican superstar: be as ridiculous as possible.

Is Rachel Maddow gunning for Scott Brown’s Senate seat? The Massachusetts Republican thinks she is. In a fundraising email sent out Tuesday afternoon, he says the state’s Democratic Party is trying to get the MSNBC host to challenge him for his newly acquired Senate seat.

“It’s only been a couple of months since I’ve been in office, and before I’ve even settled into my new job, the political machine in Massachusetts is looking for someone to run against me,” Brown writes. “And you’re not going to believe who they are supposedly trying to recruit — liberal MSNBC anchor Rachel Maddow.”

Said Brown in a fundraising email: “I’m sure [Maddow’s] a nice person — I just don’t think America can afford her liberal politics.”

Now, I realize that politicians and various political entities take certain, shall we say, liberties when writing fundraising letters. But making up imaginary rivals is usually the work of desperate fringe groups, not sitting United States senators.

For her part, Rachel addressed the subject in a very amusing segment last night.

If you can’t watch clips from your work computer, here’s the bottom line: Rachel said, “I have the best job in the world. I’m not running for office. I never said I would run for office. Nobody’s asked me to run for office.”

On a related note, the conservative Boston Herald has a report today, suggesting the Brown fad is quickly coming to an end. Bill Whalen, a former Republican operative and research fellow at the conservative Hoover Institution, compared the GOP senator to Arnold Schwarzenegger, calling both a “political novelty.”
