I'll stick with Rasmussen, thank you. Quinnipiac is a notable outlier to the left side of polling, probably by design.
The Quinnipiac poll is run by the Political Science Department of Quinnipiac University. Enough said.
Quinnipiac is heavily laced with College socialist/brainwashed students that conduct their surveys. They frequently do this. They make up much of Daily Kos, DU and the like. They “cherry pick” interviews and load the results in their favor.
Surveys such as this are not worth the time it takes to report them. Rasmussen is the best poll to watch this stage of the election. (But then, you know that...)
Those Quinnipiac polls are so far to the left the bell curve is flat lined...
