Gallup Daily today shows Obama edging out McCain for the first time since the Republican convention bounce with 47% for Obama and 45% for McCain. Since this is a three day rolling average, the effect of the economic crisis that struck on Monday is presumably just showing up in these numbers. According to Gallup daily in individual days for polling on Monday and Tuesday ratings of the US economy have become worse and Obama has had an advantage among registered voters.
These numbers still are within statistical ranges of each other. That is, the numbers show a tie between the candidates. But I predict that tomorrow will show Obama rising ahead of McCain with a statistical advantage.
