Here are 2 polls showing who is ahead so far.
CBS/New York Times Poll (compiled as of 9/24/2008):
Obama - 47%
McCain - 44%
FOX/Opinion Dynamics (compiled as of 9/23/3008):
Obama - 45%
McCain - 39%
So at this point, it is still a fairly even race and it seems that it really is anybody's game. These number I am predicting though will change after Thursday's debate.
