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
Trump could run up the margin in the rural areas though, like Hofer did in the Austrian Presidential election. There could also be higher turnout in the rural areas than the urban areas. Or not. This is all hard to tell. On the other hand, Trump is no Hofer (who, as a Far-Right candidate has slightly positive favorable ratings ...) So, while Hofer kept the Austrian suburbs close - Trump might lose them big time.
We'll see.
