Republicans take part in "Rock the Caucus"

DES MOINES, Iowa -- Caucus day in Iowa kicked off with an event that brought three of the Republican hopefuls to the gymnasium of Valley High School for "Rock the Caucus," an event meant to encourage the just-turned or about-to-turn 18 set to participate in the process.

For nearly every high schooler that packed into the bleachers, there was a member of the media there to watch as Rick Santorum, Rep. Michele Bachmann and Rep. Ron Paul made their final pitches to these would-be caucus-goers. According to Iowa caucus rules, an individual has to be 18 by Election Day to caucus for a candidate.

Santorum, flanked by his wife, Karen and six of his seven children, delivered an entreaty for young Iowans to engage in the political process.

"Every decision that's made in the next few years ... is going to be dealt with so you don't have a lower standard of living," Santorum said. "You need to hold the president, presidential candidates, the members of Congress accountable, because it's your future."
