Santorum campaign selling sweater-vests

Rick Santorum's presidential campaign is giving out "official Rick Santorum for President" sweater-vests when supporters donate at least $100.

"Perfect for demonstrating solidarity with true conservatives, this vest is a great way to show your support for Rick," the Santorum campaign's donor pitch reads. 

Santorum has received attention for the vests, which have become his sartorial trademark. In an interview on the Laura Ingraham show, the former Pennsylvania senator described how his sweater-vests caught on as a sort of symbol for his campaign.

"I was at a speech two weeks ago and I just happened to wear a sweater-vest that day," Santorum told Ingraham last week. "That speech went over very, very well. If there was one event that really began the moment, it was that speech. And I think most people recognized that here, so all the sudden the sweater-vest was like, 'Fear the vest.' "

Democrats have also associated the vests with Santorum. Rep. Chris Murphy (D-Conn.) promised to wear his sweater-vest if Santorum won the Iowa caucus.

"If Santorum wins tonight, I am overruling my staff's orders and breaking back out my sweater-vests. #argylerules," Murphy tweeted last week.
