"While much of her party’s leadership (and rank-and-file) capitulated, Pelosi – as the House minority whip – was the highest-ranking Democrat to oppose the war resolution in the fall of 2002."Nancy Pelosi's Not-So-Secret Support for Obama
by Steve Kornacki | March 17, 2008 Whatever her official posture, Nancy Pelosi is not neutral in the Democratic primary.Typically, for instance, someone who is neutral wouldn’t say that victory by one of the candidates would be “harmful.” That’s essentially how Pelosi, the supposedly impartial House Speaker, has characterized the prospective nomination of Hillary Clinton.
“If the votes of the superdelegates overturn what happens in the elections, it would be harmful to the Democratic Party,” Pelosi said in an interview for ABC’s “This Week” that was taped late last week.
That just so happens to be the only plausible scenario under which Clinton could still get the Democratic nomination from Barack Obama, who will close out the primary season ahead in the pledged delegate race and, almost certainly, in the popular vote count – even if do-overs are held in Michigan and Florida. The Clinton campaign itself has all but acknowledged this, pursuing a strategy that is designed to incite intra-party panic over Obama’s general-election prospects and to foment a mutiny by superdelegates that would deny him the nomination.
In effect, Pelosi has now said on national television that Clinton will hurt the party if she succeeds. And lest anyone think Pelosi would be willing to grant Clinton some wiggle room should she manage to surpass Obama in the popular vote count (but not the pledged delegate race), Pelosi also made her position clear on that score as well: “It’s a delegate race.”
