That’s funny.
Most people don't even know who Mitt Romney is, but, unfortunately for Hillary, everyone knows who she is. When the people in the other states get to know Mitt as well as the people in Iowa and New Hampshire got to know him, those numbers will change.
Romney's strength crosses almost all age demographics. He leads among all age categories except those aged 18–24, where Giuliani is favored by the GOPers. The older the respondent, the more likely they are to support Romney, including those in the two key demographic groups. Among those aged 35–54, he holds an 11–point lead over Giuliani with Thompson finishing third, and he leads by 27 points over Thompson among those Iowa Republicans aged 55–69.
