Today is Super Tuesday and the stakes are high for former Vice President Joe Biden and Senator Bernie Sanders (I-VT) to get as many delegates as possible to become the Democratic nominee. But just hours before the biggest day on the primary calendar, the Democratic race for President saw a major shakeup. Minnesota Sen. Amy Klobuchar suspended her campaign and a list of moderate Democrats consolidated around Biden.  Could these major developments and last minute endorsements make Biden's Tuesday super? Juan Williams, Fox News political analyst and Co-host of "The Five", previews today's 15 contests.

While the pundits and pollsters have been making predictions for months, voters in 14 states will actually head to the polls today and help determine who will be the nominee for the Democratic party. FOX's Mike Emanuel, Jonathan Hunt and Alicia Acuna are on the ground in Texas, California and Colorado and tell us what voters care about this primary season. Then, FOX's Jared Halpern explains why the number 15 is so important for the candidates today and whose campaign former New York City mayor Michael Bloomberg will impact the most.

Plus, commentary by FOX Nation host Abby Hornacek.
