Huckabee does a lot better with women than men (and we've seen this in other GOP primary polls, but usually not to this extent). He's at 27% among women and 15% among men. Ryan actually beats him among men.
Sanders at 5% hahaha, ahead of both Cuomo and O'Malley.
The very first time he's been included in these primary polls I think.
It's the first time we've seen him in an Iowa poll, but there've been a few other state and national polls that have included him. This NH poll also showed Sanders at 5% in NH, again in 4th place behind Clinton/Biden/Warren:
