The bickering Republicans presidential candidates are trying to figure out how to cash in on the largest single-day haul of delegates in the race. At stake for Republicans on Super Tuesday are nearly 600 delegates. Ted Cruz tells supporters in Atlanta to help him play the numbers game as he takes on front-runner Donald Trump and rival Marco Rubio. The Texas senator wants backers "to vote for me 10 times," but he's isn't suggesting voter fraud - "we're not Democrats," he jokes. He's appealing for each supporter to get nine others to vote for him Tuesday. Cruz calls Super Tuesday "the most important day in this entire election cycle" and says turnout is key. He says if Republicans nominate Trump, 'we'd end up electing" Democrat Hillary Clinton as president.
