The Reuters/C-SPAN/Zogby daily tracking poll again showed upward movement for Barack Obama. Obama registered 31 percent cent support, the first time in this survey that he’s broken the 30 per cent mark. Hillary Clinton dropped four points to 24 percent putting her in third place behind Obama and John Edwards, who had 27 percent. All others are in single digits. The margin of error is 3.3 percent.

Mike Huckabee slightly widened his lead among Republicans, moving to 31 percent compared to 25 percent for Mitt Romney followed by Fred Thompson at 11 percent, John McCain and Ron Paul at 10 percent and Rudy Giuliani at 6 percent where he is tied with “Undecided.” The Politico reported unnamed Republican sources close to Thompson as saying he might drop out of the race if he does poorly in Iowa. Thompson denied the report in an interview with a Iowa television station.

In New Hampshire, a Franklin Pierce College/WBZ poll showed, in the Democratic contest, that Clinton leads Obama 32 percent to 28 percent with Edwards at third at 19 percent. All others are in single digits. The margin of error is 4.9 percent. Among Republicans, McCain leads Romney 37 percent to 31 percent, a finding consistent with the upswing McCain has been showing in other polls. Giuliani, who had 28 percent in this poll in March, languishes in third at 10 percent, with all others in single digits. Margin of error for both polls is 4.9 percent.
