I think this is hysterical. I mean, progressive Pennsylvania Democrats were pretty pissed off when the Beltway pols made the deal that put the anti-choice, radical centrist Bob Casey in the Senate, and over Ed Rendell promising Specter he wouldn't face a Democratic primary challenge. These backroom deals are how a state with a large liberal voting bloc keeps ending up with conservative representation:

Senior Senate Democrats are objecting to the deal Majority Leader Harry Reid made with Sen. Arlen Specter, saying they will vote against letting the former Republican shoot to the top of powerful committees after he switches parties.

Several Democrats are furious with Sen. Reid (D-Nev.) for agreeing to let Specter (Pa.) keep his seniority, accrued over more than 28 years as a GOP senator. That agreement would allow Specter to leap past senior Democrats on powerful panels — including the Appropriations and Judiciary committees.

“I won’t be happy if I don’t get to chair something because of Arlen Specter,” said Sen. Barbara Mikulski (D-Md.), who sits on the Appropriations Committee with Specter and is fifth in seniority among Democrats, behind Chairman Daniel Inouye (Hawaii) and Sens. Robert Byrd (W.Va.), Patrick Leahy (Vt.) and Tom Harkin (Iowa). “I’m happy with the Democratic order, but I don’t want to be displaced because of Arlen Specter,” she said.

Specter’s first full day in Washington after turning the Capitol upside down with his decision to switch parties suggested a lonely future awaits in the upper chamber.

While he received a formal welcome Wednesday to the Democratic Party at the White House from President Obama and Vice President Biden, senior Senate Democrats exchanged phone calls to voice their objections to Reid’s gambit and one lawmaker said Specter should be happy with a committee seat at the “end of the dais.” Meanwhile, Senate Minority Leader Mitch McConnell (R-Ky.) and two other members of the Senate Republican leadership asked Specter to refund campaign donations.

One senior Democratic lawmaker told The Hill that the Democratic Conference will vote against giving the longtime Pennsylvania Republican seniority over lawmakers like Harkin, Mikulski and Sen. Dianne Feinstein (D-Calif.) when they hold their organizational meeting after the 2010 election.

Under his deal with Reid, Specter would jump ahead of all but a few Democrats when it comes time to dole out committee chairmanships and assignments.

“That’s his deal and not the caucus’s,” the senior lawmaker said of Reid’s agreement with Specter.
