President Barack Obama will tape an appearance for Comedy Central’s “Daily Show” program tomorrow, three days before host Jon Stewart helps lead a rally in Washington that Democrats say may boost their party’s election chances.

Obama has sought to reach beyond news programs and traditional political forums to get his message across. Last week, he taped an appearance for Discovery Channel’s “MythBusters” show as part of an effort to promote science and technology education. He also was interviewed on ABC’s daytime talk show “The View” in July, and during the debate over his health-care overhaul plan he went on CBS’s “Late Show with David Letterman.” He’s also appeared on NBC’s “The Tonight Show with Jay Leno.”

“I’m sure we’ll pull in some funny lines,” spokesman Robert Gibbs said of the president’s taping.
