"In private, he has talked longingly of 'going Bulworth'"

Yet Mr. Obama also expresses exasperation. In private, he has talked longingly of “going Bulworth,” a reference to a little-remembered 1998 Warren Beatty movie about a senator who risked it all to say what he really thought. While Mr. Beatty’s character had neither the power nor the platform of a president, the metaphor highlights Mr. Obama’s desire to be liberated from what he sees as the hindrances on him.

“Probably every president says that from time to time,” said David Axelrod, another longtime adviser who has heard Mr. Obama’s movie-inspired aspiration. “It’s probably cathartic just to say it. But the reality is that while you want to be truthful, you want to be straightforward, you also want to be practical about whatever you’re saying.”

The cinematic allusion seems striking given Mr. Obama’s rejection of Hollywood’s version of the White House, what one former aide calls “the Harry Potter theory of the presidency,” which suggests that he could wave a wand and make things happen. At the White House Correspondents Association dinner last month, he bristled at the idea that he should be pattern himself after Michael Douglas’s assertive character in “The American President.”
