Those are all robopolls, right? I've noticed a huge disparity between the Hispanic subsamples of robopolls and live-caller pollsters this election, with the former consistently showing Hispanics as much more Republican.
This inaccuracy was visible in the primary polls as well- I remember PPP in Florida consistently had Gingrich winning like 45% of Hispanics, who of course voted overwhelmingly for Romney.
Which pollster are robopolls besides PPP. They were the only ones that had Gingrich winning Hispanics in the FL primary, if memory serves me. It is likely why they so underestimated Romney's win there.
Another thing to consider is that if Romney were only getting 20% of the Hispanic vote, he couldn't even be close in FL and he clearly is.
Florida's hispanics are a different breed from hispanics anywhere else in the country, due to the Castro Factor.
