Picture the polling results in Louisiana’s Senate race between Republican incumbent David Vitter and Democrat Charlie Melancon as a conversation among polling firms:
Rasmussen, PPP, Southern Media/Opinion Research, and Magellan stand together in a crowd, exchanging results.
Pollsters: Vitter’s up by 24, Vitter’s up by 18, Vitter’s up by 9, Vitter’s up by 20, Vitter is up by 18.
Anzalone Liszt, pollster for Democrat Charlie Melancon, suddenly appears and interjects.
Anzalone Liszt: Vitter is only up by one!
(Silence. The other pollsters look at their results again.)
Rasmussen, PPP, Southern Media/Opinion Research, Clarus, Magellan: Vitter is up by 12, Vitter is up by 10, Vitter is up by 21, Vitter is up by 18, Vitter is up by 16 . . .
Anzalone Liszt, frustrated, stands apart from the others. Finally he shakes his fist at the other pollsters.
Anzalone Liszt: Vitter is only up 7!
