As Obama Launches New Budget Campaign, Who's the Opponent?

From Washingtonpost.com

That's the news this morning, with the Democratic National Committee ready to use its 13-million address email list to to mobilize supporters and flood Capitol Hill with phone calls. On the surface, this seems perfectly normal: The president is firing up his base to help get a legislative priority passed. But at whom is this campaign really aimed?
