From Fox News:

Ron Paul, the congressman from Texas and a favorite of Tea Partiers,  effectively ended his presidential campaign Monday but urged his fervent  supporters to continue working at the state party level to cause havoc for  presumptive Republican nominee Mitt Romney.

In an email to supporters, Paul urged his libertarian-leaning backers to  remain involved in politics and champion his causes despite the apparent end of  his presidential aspirations. Paul has found success in wrecking the selection  process for delegates to the party’s late-summer nominating convention in Tampa,  Fla., and trumpeted that he has delayed Romney’s expected nomination.

“Moving forward, however, we will no longer spend resources campaigning in  primaries in states that have not yet voted,” Paul said in his statement. “Doing  so with any hope of success would take many tens of millions of dollars we  simply do not have. I encourage all supporters of liberty to make sure you get  to the polls and make your voices heard, particularly in the local, state and  congressional elections, where so many defenders of freedom are fighting and  need your support.”
