While former Sen. Scott Brown dined with a group of Republican senators on Capitol Hill today, Sen. Majority Leader Harry Reid, D-Nev., had some words for the potential Senate hopeful that may be hard to stomach.

"The Constitution guarantees every state two Senators. The Constitution doesn't guarantee every Senator two states," Reid said, alluding to Brown's switch from representing Massachusetts in the Senate to exploring a run in New Hampshire.

Political jockeying for position is hardly new in national politics, but Reid seems to say that Brown's move crossed a line.

Unfortunately for Reid, Brown's candidacy would put yet another state in play for the Republicans, making the Democrats' chances of holding onto the Senate in the 2014 midterms even more of a challenge.

"We'd love to have Scott back," said Sen. Minority Leader Mitch McConnell, R-Ky. "We're happy that he's running for the Senate. He's an old friend of ours. And no one's election victory was more a symbol of public objection to Obamacare like Scott Brown's special election in January of 2010."

Senate Republicans welcomed Brown back to the policy lunch he used to attend weekly when he was a sitting senator, but Brown isn't the first hopeful who has graced the weekly event. Rep. Cory Gardner, who is running in Colorado, as well as Shane Osborn, who is running in Nebraska, both attended lunches earlier this year.

Brown's trip to the Capitol came just one day after his exploratory committee released a scathing memo, blasting incumbent Sen. Jeanne Shaheen, D-N.H., of trying to "throw up one smokescreen after another in an attempt to avoid discussing the issues."

It went on to call Shaheen "a reliable rubber stamp" for the Obama administration's agenda and Shasheen's work "disappointing and a disservice to New Hampshire."
