Zogby has Huckabee and Obama comfortable:

UTICA, New York – Democrat Barack Obama continued his upward momentum through the evening before the Iowa caucuses, capturing the lead ahead of rivals John Edwards and Hillary Clinton.. Meanwhile, Republican Mike Hucakbee widened his lead over Mitt Romney down the stretch, the newest and last Reuters/C–SPAN/Zogby daily telephone tracking poll in Iowa shows. Obama broke through the 30% barrier for the first time, gaining 31% support after another strong day leading up to the caucuses. But more dramatic was Clinton’s four-point drop in this last day of tracking. Edwards moved into second place by himself after another day where he steadily gained ground. This fifth and final daily tracking poll was conducted using live telephone operators in the Zogby call center in Upstate New York. Edwards finished this Zogby daily tracking in Iowa in the same place as four years ago, when Zogby correctly identified the finishing order of the candidates in that caucus.
