Watch out, John McCain. You too, Barack Obama.

Michael Moore is coming out with a new book. "Mike's Election Guide," a manual of mockery for the 2008 presidential election, will be published Aug. 19 by Grand Central Publishing. Promotional material for the book reads: "Perfectly timed to coincide with the national political conventions - and to capitalize on massive campaign coverage."

Moore, 54, won an Academy Award for best documentary with his 2002 gun-control film "Bowling for Columbine." Ahead of 2004's U.S. presidential election, the director-activist released "Fahrenheit 9/11," his top-grossing film condemning the war in Iraq.

Moore's previous book - 2003's "Dude, Where's My Country?" - sold more than a million copies.
