The actress, 52, explained, “We keep this entirely fictional only because we don’t want to align ourselves with one party or the other. And in addition to that, we think it’s important to keep this world very much a fantasy political world and unidentifiable in terms of partisan politics.”

We caught up with Louis-Dreyfus at a Thursday screening of “Veep’s” second season at the Motion Picture Association of America headquarters in downtown Washington.

Biden hasn’t publicly pined to be on “Veep,” but California Lt. Gov. Gavin Newsom has. The Democrat gushed to ITK earlier this year that he’s a huge fan of the HBO series. Saying he “desperately” wants to go on the show, Newsom, 45, exclaimed, “I figure I’ve almost written my scene.”

While she’s a “supporter” of Newsom, Louis-Dreyfus said, “I don’t mean to disappoint him, but I’m going to have to disappoint him because we’re not going to use real political players on the show.”
