The USA Today Gallup poll is more than likely an outlier. Rasmussen daily tracker is better gauge followed by the Gallup daily tracking. Rasmussen has McCain up 1 point M 48 O 47. All interviews were taken after the GOP Convention.
With the “right track wrong track” numbers such as they are you would think Obama would be further ahead. It makes me wonder if the electorate is weary of another round of One Party Rule.
