Presidential hopeful Ron Paul takes aim at the three candidates getting the most attention in the GOP race, blasting Mitt Romney, Rick Perry and Michele Bachmann as "smooth-talking politicians" in the same company as President Obama.

The Texas congressman, who finished second to Bachmann in last weekend's Iowa straw poll, highlights his votes against "every tax increase, every unbalanced budget" and proclaims he is the candidate who "will stop the spending, save the dollar, create jobs" and "bring peace."

Images of Perry, Romney and Bachmann -- along with Obama and House Minority Leader Nancy Pelosi -- roll by throughout the ad. The script begins by describing a story of "smooth-talking politicians" and "games of he said, she said."

The ad will air in Iowa and New Hampshire, where the first presidential nominating contests will be held in February.

The intensity and direction of the race for the GOP nomination shifted after the Iowa straw poll Aug. 13, and much of the focus is now on Romney, Perry and Bachmann.

Paul's supporters have been ardent behind his message of no government intrusion and helped him do well in Ames over the weekend. He has also been able to deploy the Internet as a fundraising tool.

Romney, a former Massachusetts governor, has led in national polls by Gallup and other organizations and is the clear front-runner in New Hampshire. Perry, the Texas governor, shot up to second behind Rommey in national surveys even before he formally entered the race Saturday.

Bachmann has been doing well in Iowa, according to polls in the Hawkeye State. Paul fared better than she did in the latest CNN national survey (12% vs. 7%), but Rommey and then Perry were at the top of that poll.
