My money is on Pelosi is behind Murtha's challenge of Hoyer for Majority Leader.
Murtha is one of Pelosi’s top allies in the House, one of the architects of her 2001 victory over Hoyer. Earlier this week, Hoyer publicly pledged his loyalty to Pelosi, saying that he wants her to lead the Democrats whether they win or lose this fall.
Maybe Murtha is going to shoot for Majority Leader now that he is a famous Democrat outside the beltway and respected inside it. I bet that Pelosi is starting to create her own leadership team.
A bit premature if you ask me.
