Donald Trump and Hillary Clinton are expected to roll to victories in the South, leaving their rivals trying to scrape for wins elsewhere on the biggest voting day of the year so far.

In important Super Tuesday states with a high number of born-again voters, Ted Cruz is losing to Donald Trump, and Marco Rubio is eating into his support with evangelicals.

On CNN's State of the Union, the Republican front-runner was asked if he'd distance himself from the support of former KKK grand wizard David Duke. Trump refused four times, saying, "I don't know."

Trump's successes endanger both Cruz and Rubio. Will this be the debate where they stop fighting each other and take on Trump?

The real estate mogul is once again the favorite to win the Silver State's caucuses, with Texas Sen. Ted Cruz and Florida Sen. Marco Rubio also battling for a strong finish.

Hillary Clinton's big problems: She's not winning women, and voters still don't trust her. Meanwhile, Donald Trump's support is broad and deep.

Marco Rubio was the surprise beneficiary of heavy GOP turnout and made the fight for evangelicals a three-way contest. Bernie Sanders won with younger voters, but not enough voted for him to win.

The latest Iowa Poll shows a much closer race between Trump and Cruz if evangelical voters turn out at the same level they did four years ago.

Television debates have been a mainstay in presidential campaigns since 1976. Now, the GOP presidential front-runner is taking a big gamble just days before the Iowa caucuses.
