So here's our Election Central guide to the Dem leadership fights which have kicked in now that Dems have taken back both Houses of Congress. There's less intraparty battling going on right now among Dems than among Republicans, but there's a key fight to watch, of course, in the battle between Reps. Steny Hoyer and Jack Murtha for House Majority Leader. Check out our full roundup after the jump.

The House

Speaker of the House

Current House Minority Leader Nancy Pelosi is poised to become the Speaker of the House. The Los Angeles Times has an extensive profile of Pelosi here.

House Majority Leader

The big fight for Dems is the clash for House Majority Leader between current House Minority Whip Steny Hoyer and Rep. John Murtha, who has been a leading Democratic voice calling for withdrawal from Iraq. The war in Iraq is a key division between the two lawmakers as Hoyer refused to support a withdrawal resolution that Murtha introduced last year. The Hotline reports that while neither camp has released a list of supporters, Hoyer leads with 39 commitments of support to Murtha's 15.

* Rep. Steny Hoyer (D-MD)

Hoyer, the current Whip, has already recieved a joint letter of support from various senior Democrats including Barney Frank, John Lewis, Henry Waxman, Lucille Roybal-Allard, Ellen Tauscher, James Oberstar and Ike Skelton. He has also recieved a pledge of support from at least 21 of the 41 newly-elected Democrats in the House. As a recent Washington Monthly profile laid out, Hoyer is considered a centrist on foreign policy issues, an "establishmentarian" and the leadership's unofficial liason to the conservative Blue Dog Democrats caucus.

Hoyer and Pelosi have had public ideological splits in the past, especially concerning Iraq. Read Hoyer's letter declaring his candidacy for Majority Leader here.

* Rep. John Murtha (D-PA)

Murtha, the Ranking Member on the House Appropriations Sub-Committee on Defense, recieved a boost for his leadership candidacy on Sunday when soon-to-be Speaker Pelosi sent out a letter of support for him. Reps. George Miller (D-CA), Kendrick Meek (D-FL), and John Larson (D-CT) have been actively soliciting support for Murtha from newly-elected House members.

Though Murtha has at times been tagged as a pro-military social conservative (he's pro-life), his opposition to the continued U.S. presence in Iraq, his aggressive confrontations with the White House, and his economic populism have made him a favorite of the party's liberals. Nonetheless, Murtha's "long reputation for porkbarrel politics and `back room' deals," as TPMmuckraker's Justin Rood aptly puts it, could complicate the Dem leadership's efforts to claim they're bent on cleaning up the GOP corruption that caused voters to turn on the Republicans.

House Majority Whip

Democrats avoided a fight for this position when Rep. Rahm Emanuel (D-IL), who successfully headed the DCCC's re-election efforts, agreed to seek the House Democratic Caucus Chair, paving the way for current Caucus Chair Jim Clyburn (D-SC) to ascend to the #3 position in the House. Rep. Diana Degette (D-CO) has expressed interest in running, but has yet to announce her candidacy. For background on Clyburn, check out this Post and Courier article.

The Senate

With no members of the Democratic Senate leadership retiring, the current leaders are expected to continue in their roles while in the Majority.

Senate Majority Leader

Sen. Harry Reid (D-NV) is expected to continue in that position as no challengers have arisen in the Democratic ranks. Check out this recent New York Times profile on him.

Assistant Democratic Leader (Whip)

Sen. Richard Durbin (D-IL) is expected to continue in this leadership role. For a profile on Durbin, check out this article from The Nation.

Secretary of the Conference

Sen. Debbie Stabenow (D-MI), who successfully got re-elected last week, will likely continue in her function as Secretary of the Conference, though she is also being considered for a spot on the Senate Finance Committee.
