Barack's Bounce

Barack got a nice bump out of the convention. How long it survives Sarah Palin will be fun to watch. The Gallup Poll shows Barack up 8 points, and Rasmussen, the more reliable of the two, gives Obama a 4 point lead.

The Rasmussen Reports daily Presidential Tracking Poll for Friday shows Barack Obama attracting 46% of the vote nationwide while John McCain earns 43%. When "leaners" are included, it’s Obama 49% and McCain 45% (see recent daily results).

This is Obama’s biggest lead since late July, when he opened up a six-point advantage following his summer speech in Berlin.

This bump will likely disappear as fast as the Berlin bounce did.
