Clinton 47
Sanders 45
"Jeb Bush (3.8 percent), Mike Huckabee (3.7 percent) and Carly Fiorina (1.1 percent). Rick Santorum, Chris Christie and John Kasich registered less than 1 percent"
The new ISU/WHO-HD poll was compiled through phone interviews with 722 registered voters Jan. 5-22
And looking at the day, I guess this is why. Cruz was leading in early January.
