An analysis of historical election poll trends by Gallup Poll Managing Editor Jeff Jones shows that recent presidential campaigns have enjoyed a small (though short-lived) bounce from the running mate announcement. This includes a four percentage point bounce for John Kerry in 2004 after selecting John Edwards, a 5-point bounce for Al Gore in 2000 with his announcement of Joe Lieberman, and a 3-point bounce for George W. Bush in 2000 upon choosing Dick Cheney. Bob Dole received an extraordinary 9-point bounce in 1996 after bringing Jack Kemp onto his ticket.
