Presidential candidate Rick Santorum says he's got the courage to do the impossible and that's the reason Republicans should pick him to run against President Obama in 2012.

"The Courage to Fight for America" is his campaign slogan, but in this new ad, Santorum isn't talking about his strong social stances or his determination to combat terrorists at home and abroad.

No, no. This ad highlights the courage... to drive thousands of miles with seven kids.

The ad shows a funny, approachable side to Santorum that may prove just as important as the issues to some voters. Santorum hopes to do well next week in the first substantial test of 2012 -- the Ames straw poll.
