PA: Survey USA: Obama up 15 in PA

[Tender Branson]

McCain loses 21% of Republicans? Yeah right. Plus exit polls had the state as D+2, this D+11 party ID doesn't pass the smell test.

I wouldn't be so sure about it:

In 2004, Democrats had a 7% registration advantage and the exit polls showed a 2% advantage for them.

In 2006, Democrats also had a 7% registration advantage in PA, and exit polls showed them with a 5% lead.

In 2008, the registraion advantage grew to 14% ...

So, if the additional 7% are added to the 2006 numbers, what is the result ?
