(CNN) - Texas Gov. Rick Perry is at the top of the Republican presidential field in another national poll.
According to the Gallup survey released Wednesday, Perry leads the pack among Republican and Republican-leaning independents with 29 percent, followed by former Massachusetts Gov. Mitt Romney at 17 percent, Rep. Ron Paul of Texas at 13 percent and Rep. Michele Bachmann of Minnesota at 10 percent.
The other GOP candidates received fewer than 5 percent.
In a July Gallup poll, taken before Perry officially jumped into the race, Romney was ahead with 23 percent, followed by Perry at 18 percent.
The new poll surveyed 1,040 voters via telephone between August 17 and August 21 with a sampling error of plus or minus four percentage points.
