Don�t Paul the primary is over. He�s too busy mucking up Mitt Romney�s efforts to accumulate enough convention delegates to claim officially the Republican nomination for president. Paul�s supporters won control of state GOP conventions in Maine and Nevada last weekend, stripping Romney of delegates in Maine but graciously letting him keep the ones he won in Nevada�s February caucuses. Next up are Republican state conventions in Minnesota, Missouri, Louisiana and Iowa. (AP Photo/Robert F. Bukaty, File)
Texas congressman Ron Paul says he is done spending money on his campaign for the Republican presidential nomination.
Paul on Monday issued a statement that insisted he would continue the fight for delegates, taking the battle to the GOP convention in Tampa.
But the favorite of libertarians and tea partyers said he would no longer spend "many tens of millions of dollars we simply do not have."
Mitt Romney is 178 delegates shy of the 1,144 needed to capture the nomination, and Paul faces an all-but-impossible task of catching him.
Paul's supporters have been causing trouble at local delegate selections but are unlikely to derail Romney's route.
Paul, a longtime congressman, is not running for another term to represent his Texas district.
