A new Gallup poll of the national Republican race shows Rudy Giuliani’s support slipping to its lowest level since before he entered the race. The survey of self-identified Republicans and Republican leaners has Giuliani leading the GOP contest with 28 percent – down from 34 percent in the Gallup survey taken two weeks ago. Fred Thompson is second with 19 percent, John McCain is third with 13 percent, Mitt Romney is fourth with 12 percent, and Mike Huckabee is fifth with ten percent.

Giuliani’s support reached its highest point in Gallup polls, 49 percent, in March. In the months since, it has moved around in the mid- to low-30s range. Of the other candidates, McCain is down a bit from recent Gallup polls, while Huckabee’s ten percent is three points higher than it has ever been before. Finally, Ron Paul is at five percent, which matches his previous high point, reached last month.
