Will Ferrell and Zach Galifianakis to campaign at the National Constitution Center

Bitter political rivals Cam Brady (who suspiciously looks like Will Ferrell) and Marty Huggins (who bears a striking resemblance to Zach Galifianakis) will hold a rally for their respective campaigns at the National Constitution Center on Tue., July 31.

The rally will promote Ferrell and Galifianakis' new flick "The Campaign," which hits theaters Fri., Aug. 10 and will feature a special proclamation by NCC CEO David Eisner. The rally starts at 11 a.m. (although doors open at 10 a.m.) and is free to the public, whether have vote ID or not.

While we get that this all fun and games, President Galifianakis has a nice ring to it, no? Check out the trailer below:
