Ron Paul: 'We will no longer spend resources'

WASHINGTON — Ron Paul, the congressman from Texas and a favorite of tea partyers, 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.
