Quinnipiac is one of the polls that CNN will include in their average to determine who will be in the primary debate. Fortunately for us, there's already like a month and a half worth of polls that will be included where Rand is doing much better.
RCP average from national polls since 7/16:
Trump 22.6
Bush 11.6
Walker 10.6
Carson 7.5
Rubio 6.4
Cruz 6.2
Huckabee 5.9
Paul 4.6
Kasich 3.6
Christie 3.3
Fiorina 2.6
Perry 1.9
Santorum 1.3
Jindal 1.2
Graham 0.4
CNN has not ever said they will use any specific poll - at least to my knowledge - if they do
then they succumb to any of the errors in those methodologies, particularly Qunni U.
Internet media sources and bloggers can think or speculate what they want,
but it IS CNN and Reagan Foundation that co-sponsor this debate.
