Ron Paul: I'm the 'flavor of the decade'

Republican presidential candidate Ron Paul on Sunday continued the trend of presidential candidates comparing themselves and others to ice cream.

A recent poll of likely Iowa caucus-goers by The Des Moines Register has Paul in second place behind former House Speaker Newt Gingrich.

"We've had the flavor up the month up and down so far in this campaign," Paul told CNN's Candy Crowley. "I like to think of myself as the flavor of the decade."

"We keep plodding along on a couple of issues that are really striking a cord with the people. And that is, of course, the wars, the endless wars going on as well as the financial condition of the country."

After Herman Cain rose to the top of some polls in September, failed Republican vice presidential candidate Sarah Palin referred to him, who she called "Herb," as "the flavor of the week."

Within a week, Cain had embraced the idea, saying that "black walnut isn't a flavor of the week."

Cain later told GQ magazine that most of the other Republican candidates were like ice cream too. Former Massachusetts Gov. Mitt Romney was vanilla, Texas Gov. Rick Perry was rocky road and Rep. Michele Bachmann was tutti-frutti.

Paul, however, was "just not an ice cream flavor," Cain said.

Cain suspended his campaign Saturday after at least three women accused him of sexual harassment and another claimed she had been involved in a 13-year affair with the candidate.
