Keep in mind that a) this is Quinnipiac which are Clinton’s pollsters so either Dems are oversampled or, possibly in this case, undersampled to try to encourage a Democrat challenger to Obama. And b) this is “registered voters”, not “likely voters”, which tells us they were already trying to help Obama’s chances since RV polls tend to lean more left than LV polls, particularly when LVs are upset at the current party in power.
What is wrong with that 42%? Are they nuts?
