Romney is frontrunner for the first time, by a whopping and meaningful one point:
--snip--
"In the race for the Republican Presidential Nomination, five candidates are within five points of the lead. On the morning of the Iowa caucuses, the Republicans now have their fifth “leader” of the season as Mitt Romney winds up on top for the first time ever. But, his advantage is a statistically insignificant one point and reflects the continuing lack of a GOP frontrunner. It’s Romney 18%, John McCain 17%, and Mike Huckabee at 16%. Five points off the pace are Rudy Giuliani and Fred Thompson at 13%. Ron Paul retains his base support at 7% (see recent daily numbers). "

Rudy went from being the front-runner to dead last in a matter of weeks, though they're all a close-together muddle, relatively speaking. No enthusiasm for any one candidate spells eventual doom for the GOP this year.
