Remember Ron Paul?
The iconoclastic GOP presidential candidate was never a truly serious candidate to win the nomination this year, but he was an invaluable part of the process early on, especially during those many debates that seemed to have taken every other week for several months in the fall and winter of 2011/2012.
With five primary elections scheduled for Tuesday, Paul will be back in the news again collecting votes from his supporters, as will be fellow also-ran Newt Gingrich. Neither man has conceded in their race for the Republican nomination. Mitt Romney's one serious challenger, former Senator Rick Santorum, dropped of the race earlier this month.
On CNBC Monday morning, Paul said he would continue to run in a "modified" way even after Romney grabs the 1,144 delegates necessary to win the Republican nomination.
