Delegates are "electors" who are committed to supporting a particular candidate at the Republican convention in August, which will be referred to the candidate who will face Barack Obama. Senator Graham also noted that former Senator Rick Santorum had done "an outstanding job starting from almost nothing to become a serious rival in this campaign." Similarly, Newt Gingrich "has risen two or three times" in the race.
