With final results in from Tuesday’s caucuses and primary, former Pennsylvania Senator Rick Santorum pulled off large margins of victory in three non-binding nominating contests, all marked by low turnout. In Missouri, which held a primary but will not use the results to award delegates, Santorum got 55.2 percent of the vote. Former Massachusetts Governor Mitt Romney got 25.3 percent, and Texas Representative Ron Paul got 12.2 percent. Former House Speaker Newt Gingrich did not appear on the ballot. There were just under 252,000 votes cast, according to the Associated Press tally, less than half of the 588,000 votes that were cast in the Republican primary in 2008.
