A Gallup Poll, conducted 10/4-7 and released on the eve of the big Republican debate today in Dearborn, Michigan, shows Rudy Giuliani still in command of the race, at least nationally. The poll surveyed 409 Republicans and leaners, for a margin of error of approximately +/- 5%.

The big news: Former Arkansas Gov. Mike Huckabee seems to be on a measurable rise. Huckabee is at 7%, up from 1% as recently as May, while candidates like Mitt Romney have remained largely stagnant, finishing at 9% today, down just 1% since May.

Primary Election Matchup
Giuliani 32 (+2 from last poll, 9/14-16)
Thompson 20 (-2)
McCain 16 (-2)
Romney 9 (+2)
Huckabee 7 (+3)

Taking a look at the favorable ratings for each candidate, John McCain and Rudy Giuliani have little upside remaining. Both are very well-known -- just 13% have not made up their minds about Giuliani, and 15% remain undecided about McCain. High name identification is a good thing, but when people have yet to make up their minds about other candidates, it means those candidates have more of a potential upside.

For Fred Thompson and Mitt Romney, about 40% of the electorate still needs to learn more about them before formulating an opinion. Those who can learn more about Huckabee: 65%. Thompson, Romney and Huckabee have the potential to win many more supporters, while fewer new voters are available to flock to McCain and Giuliani.

Giuliani 72 / 15
