I would not put too much faith in Zogby .He has not been right much since he said Kerry would win
Look at Real Clear Politics or Rasmussen for more  reliable polls.

last week which said Obama had a 10 pt lead in Ohio. Any statistician would discount this poll as an outlier and eliminate it completely.

Truthfully all polls have been off all year especially on the democratic side. I attribute this too the fact you have a woman and an African American as the leading candidates.

Pollsters simply have not figured out how to factor a women and AA when polling, much less the voters. The old metrics of polling when the leading candidates where two white men simply are not working.

It will be the same in the general polls when BO or HC is the nominee. A simple tear can turn the whole election upside down!

My only prediction is after labor day is this election is going to get really, really ugly as in the ugliest election in U.S. history before even hildabeast announces she is running for 2012 already or as an independent.

Also, this is going to be really close, not Bush-Gore close, but closer than Bush-Kerry. It will come down too a couple thousand votes in any one state and go either way.

His poll numbers are always 10 to 20 points higher than every other Poll. He must be polling members of Trinity or South side of Chicago.

He is also an Obama surrogate.

Throw away the two high and two low poll numbers and see what you get, McCain is leads Obama.

Averaging Poll numbers! Who came up with this statistically incorrect idea, media like Real Clear Politics and CNN.
