The first thing which jumps out is the continued increase of confidence in Gov. Mitt Romney. Polling at just five percent four months ago, he has now worked his way into 19 percent of the respondent’s hearts and has morphed the GOP contest into more of a three-way race.

The way the numbers are distributed for the Republican candidates, it appears that most of the support Romney gained came from his opponent Rudy Giuliani. If that is the case, it will be interesting to see if this a temporary bounce due to Giuliani’s own press issues these past few days.

Not much has changed for the Iowa Democrats. Most notable in the numbers is the three percent increase for Gov. Bill Richardson, although this — and all the pluses and minuses up and down the board — fall well within the margin of error.

On both sides of the aisle there seem to be many individuals who have yet to make up their minds.
