Ron Paul backers have secured 12 of 13 delegates at Minnesota' state GOP convention, according to a source who was there and is familiar with the delegates' leanings.

Saturday's convention gives Paul 32 of Minnesota's 40 delegates to the Republican National Convention in Tampa, Fla., after his strong showing in the state's congressional-district conventions.

Paul announced on Monday he would no longer campaign in new states but would continue to organize at conventions to secure delegates in states that have already voted.
