In recent days, former U.S. Sen. Rick Santorum of Pennsylvania shows clear signs of making a second run for the Republican presidential nomination in 2016.
Despite fundraising problems, despite being dismissed by many political experts early in2012, Santorum placed second in the Republican primaries behind Mitt Romney. Rallying social conservatives to his banner, Santorum took almost 4 million votes (more than 20 percent of all ballots cast) and won 11 primaries and caucuses, including edging Romney by 34 votes in Iowa.
