These polls suggest that Clinton is up by 7-10 points...
The poll ended on Thursday, so we can only guess where the state is now. But, I agree with you. The Lehigh Valley is not the Philly suburbs. I think Hillary is running very strong in the Philly suburbs. If you want to see a suburban Republican collapse, look at Ed Rendell's numbers there in 2006. Even running several points behind that result would easily overrun anywhere Trump is overperforming.
Yup - if Clinton is over-performing in Berks/Bucks/Montgomery etc... then a 2012-like performance here, does suggest somewhere closer to 7-9 to me
