Rand Paul Holds Caucus Day Rally In Des Moines

Kentucky Senator Rand Paul is suspending his presidential campaign.  Paul released a statement this morning saying he's dropping out of the GOP race to focus on being re-elected to the U.S. Senate.  He said it's been an "incredible honor to run a principled campaign for the White House." 

He added that he's ending where he began -- "ready and willing to fight for the cause of Liberty."  Paul has been lagging in the polls and finished fifth in the Iowa caucuses, getting just four and a-half percent of the vote.  

The freshman Senator is popular with libertarian voters but was unable to build any momentum in his bid for the Republican nomination.
