As Deano mentioned yesterday... it IS Zogby... and the tiny nature of the lead in Iowa was not that impressive, but in New Hampshire its quite a different story:
Romney: 35%
Giuliani: 19%
McCain: 19%
As I predicted a few days ago... ideas lead the way, and Romney's most recent ad, "I Like Vetos!" is the kind of thing that voters of every stripe will resonate with.
