Their results have been all over the place, but that isn't necessarily a bad thing. A major problem in 2012 and 2014 was the polls herding together. We need pollsters to put out what they actually found, instead of reweighing or discarding polls that "don't look right."
Sure - but it is a valid observation they've certainly been expecting severely depressed Dem turnout.
Quinnipiac has been consistently releasing R-leaning polls for quite a while/
Their final 2014 Florida poll had Crist up by 2. In 2012, they had Obama up by 1 in Florida, 5 in Ohio, and 4 in Pennsylvania. Does not seem particularly indicative of a Republican bias to me.
