Bitter Effect in PA?

It's ARG, not exactly the gold standard, but maybe a portent of things to come. This is one of those situations where the movement may be more important than the actual numbers. Anyway, ARG's latest poll shows Hillary with a shocking 20 point lead over Barack in Pennsylvania, when a week ago they were tied 45-45. Today's numbers are 57-37. That's either some extremely bad polling data, or one heck of a vote shift. Could Obama's 5-1 on-air advantage be backfiring?

10% of all likely Democratic primary voters say they would never vote for Hillary Clinton in the primary and 24% of likely Democratic primary voters say they would never vote for Barack Obama in the primary.

23% of likely Democratic primary voters say that excessive exposure to Obama's advertising is causing them to support Clinton.

If so, we have real evidence that Obamania doesn't age gracefully or work well with force feeding. Also note that the began to be reported widely during part of this poll's calling period. May have had some effect. I will be extremely interested to see some other polls out of PA soon.

Drudge is also reporting that McCain has his fingers crossed... for Hillary. He has 14 press releases taking on Obama and only three for Hillary.
