Jonathan Weisman and Lois Romano set the stage in the Washington Post this morning:

A showdown over the House majority leader's post today has Democrats bitterly divided only a week after their party took control of Congress and has prompted numerous complaints that Speaker-designate Nancy Pelosi (Calif.) and her allies are using strong-arm tactics and threats to try to elect Rep. John P. Murtha (Pa.) to the job.

Jules Crittenden writes on his new blog that he's going to 'sit back and enjoy' the fight:

Today offers the kind of spectacle that is a small consolation prize for a party out of power: the victors pummeling each other over the spoils. The election having been lost, today's majority leadership race is a win-win.

Michael Barone looks at why Pelosi is so determined to support Murtha before concluding:

The word from Capitol Hill has been that Steny Hoyer, the current minority whip who ran against Pelosi for that job in 2001, has the votes. Hoyer is an experienced and competent politician who is respected and well liked on both sides of the aisle, and I suspect that many House Democrats are miffed that Pelosi is opposing him.

Murtha is telling people he's got the votes, so today's vote should be very interesting - and potentially surprising, too, since it's a secret ballot.
