Rep. Michele Bachmann's presidential ambitions will be stifled if she does win the Iowa presidential caucusses, Ed Rollins, Bachmann's former campaign manager, told MSNBC on Monday.

Rollins, who stepped down from Bachmann's campaign earlier this month, said the Minnesota congresswoman does not have the ability or resources to go beyond Iowa at this point. He suggested that Texas Gov. Rick Perry and former Massachusetts Gov. Mitt Romney are better positioned to run an extended campaign to win the Republican nomination.

She doesn't have the ability or the resources to go beyond that, Iowa, at this point and time, where Perry and Romney, with lots of money can go into South Carolina, Arizona, Florida and other places, Rollins said, while appearing on MSNBC's Andrea Mitchell Reports.

Rollins suggested that some of Bachmann's recent misteps -- such as making a link between the HPV vaccine Gardasil and mental retardation -- have come from her lack of experience on the national stage. He pointed to the fact that Bachmann has never run in a statewide race, unlike both Perry and Romney.

Rollins, a veteran GOP strategist who ran Ronald Reagan's 1984 campaign, said health issues caused him to resign from Bachmann's campaign. His deputy, David Polyansky, also stepped down, although he did not give a reason for his departure.
