I think that national poll means nothing especially now.  If we were to look at the national poll than Al Gore were to be president in 2000 as it is the number of electors that wins presidency not the popular vote.  Like the two previous elections, this one will come down to FL, OH and PA and whoever wins the two will win the election.  One important thing to notice here about Obama victory is that he has won most of the red state like UT, GA, ND, ID,SC etc.  Although, the turnout was pretty good for the donkeys on these states during primaries will still falls for the elephants in general.  It will be very difficult for Obama to win on FL and OH in November against McCain.  He may win PA but Hillary has better chance of winning FL and PA.  So in that scenario I think Hillary has better chance in November.
