The Quinnipiac polling in Pennsylvania, Ohio, and Florida, have a very tight race between Clinton and Trump. But, as Mark Murray is pointing out, we do need to consider the NBC/WSJ/Marist polling too.
NBC/WSJ/Marist battleground polling over past 2 months:
FL: Clinton 49, Trump 41
OH: Clinton 48, Trump 42
PA: Clinton 54, Trump 39

Therein lies the problem.
We need some polling averages to get a sense of this. The numbers are going to jump around a bit, but the polling averages will help balance them out.
