According to the Globe article, it's all very clear: Pelosi's facing a rebellion within her party because of the on-going CIA story:

Her decision to take on the CIA may have been intended to preserve her credibility in liberal circles, but it stirred up a firestorm among moderates and conservatives of both parties who rushed to back the intelligence community. Now, the controversy is likely to become a test of President Obama's leadership - not to rally the country, but to quell dissension in his own ranks.

According to the Globe, there is dissension within Democratic ranks over Pelosi. (And only Obama can quell it!) And specifically, “moderates” in the party have backed the CIA--not Pelosi--in the intelligence dispute.

Slight problem though, the Globe article never supplies any evidence to back up the claims. None. Who are the unnamed moderate Democrats who have bailed on Pelosi? Readers have no idea because none are ever mentioned or quoted.

But as we mentioned earlier today, the Pelosi story has progressed to that state where the press stopped bothering with the facts because everybody just knows the preferred storyline.

UPDATE: From Wednesday's WashPost:

[House Majority Leader Steny] Hoyer, a former Pelosi rival in leadership elections, added that not a single member of the Democratic caucus has questioned him about Pelosi's stance, and he said it has not been a point of discussion in leadership meetings.
