Push Polling in PA-7?

Swing State Project is reporting that there may be push polling against Joe Sestak in the 7th Congressional District. There seems to be something going on so if you live in Delaware County take notes if someone calls and be sure to ask who paid for the poll. Then contact them at either info@sestakforcongress.com, or 610-891-8956. This is Congressman Curt Weldon's District. If you received one of these calls also contact them with any information you can provide.
