All eyes on Super Tuesday
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 on Super Tuesday are 595 delegates in 11 states.
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 is not suggesting voter fraud. "We're not Democrats," he joked as he appealed for each supporter to get nine others to vote for him on Tuesday.
Cruz called Super Tuesday "the most important day in this entire election cycle" and said that turnout is key.
He said that if Republicans nominate Trump, 'we'd end up electing" Democrat Hillary Clinton as president.
In the meantime, aspiring first lady Jane Sanders says the Bernie Sanders campaign is looking to Super Tuesday when, "I think we'll split the vote".
Expecting a loss in the South Carolina primary, the Vermont senator flew to Texas yesterday morning and was heading to Minnesota later in the day.
Jane, Bernie's wife, and one of his top campaign advisers, said that South Carolina voting has already started and the campaign has to focus on March 1, when 12 states will cast ballots.
According to Jane Sanders, they are hoping for a "good showing" in South Carolina. She added that it has been hard for people to get to know Bernie Sanders there, noting: "the media didn't cover him from May to December. There was nothing in the national media. So, of course, the South didn't know him."
Still, Jane Sanders says the campaign is feeling good.
"We always knew where we would do well and where we would not do so well," she said. "It's a 50-state election and we're feeling very confident, actually."
