It seems that her efforts to put the brakes on the troop surge are meeting resistance from other Democrats. AJ-Strata discusses the situation.
Here's the problem. It's going to be easy for Democrats to defy her. The biggest reason is Majority Leader Steny Hoyer, who trounced Pelosi's pick for the job by about a 2-to-1 margin. And she did not have much of a majority - only 15 seats need to flip to give it back to the GOP.
It won't take that many Democrats defecting on the war to kill any effort to stab the troops in the back. Then, Pelosi will get it from both sides.
