They are not. In fact Crooked Hillary has pretty much written off PA, only campaigning in Philadelphia. Why would she even bother with Philly if she thought she had the state locked up? Well she needs 120% of the Philly vote instead of the traditional 110%.
Polls are typically using 2012 turnout methodology when we know that Republican enthusiasm is much higher this year based on the primaries. If polls were using R +1 instead of D +5 turnout models we would have polls closer to reality. Then add in that Trump has double digit lead among Independents.
Trump has campaigned in CT, WI and CO - states you normally don’t see a GOP candidate travel to.
Hillary hasn’t traveled much since her convention ended in late July.
While we certainly have the enthusiasm, I wouldn’t count on an R +1 advantage on Election Day. The machine will get many Democrats to the polls...multiple times
Many times they poll much higher. Yougov poll was D +16% yesterday.
