Please stop posting clearly junk polls. You expect us to believe that over 30% of Americans are undecided?
This one is no where near a junk poll. Madonna's poll have an exceptionally good record.
When neither candidate is even at 40%, it's junk.
No, Madonna doesn't push the undecides, like Rasmussen. All his early polls show this.
A 380 sample size is quite valid.
This one is not junk, and this is following Quinnipiac poll of two weeks ago.

Obama's national numbers have been declining since then.
Quinnipiac's sample size was 1,358 people. Almost 1,000 more than Muhlenberg College. 380? Come on. That is a complete joke of a sample size for a state with over twelve million people.
Junk.
Also, the Quinnipac article you posted said he fares better than both political parties. Everyone disapproves of everyone.
