It's always one of the biggest dates on the campaign calendar.
Super Tuesday has more presidential primaries than any other day, and this year a third of the Democratic Party's pledged delegates were up for grabs.
The night was a very good one for former Vice President Joe Biden, with projected wins in at least nine states: Alabama, Arkansas, Massachusetts, Minnesota, North Carolina, Oklahoma, Tennessee, Texas and Virginia. It confirmed that his campaign momentum is for real following his first victory Saturday in South Carolina.
US Sen. Bernie Sanders came into Super Tuesday with three wins, and he added a few more with projected wins in Colorado, Utah and his home state of Vermont.
The biggest prize of the night — delegate-rich California — was still up for grabs as Tuesday turned to Wednesday. Maine was also too close to call.
Unlike the general election, there are no winner-take-all states in the primaries. Any candidate who receives more than 15% of the vote in a state will win delegates to July's convention in Milwaukee.
It was still a disappointing night, however, for US Sen. Elizabeth Warren and former New York City Mayor Michael Bloomberg, who both needed to make a statement to have a rationale for staying in the race. Warren finished third in her home state of Massachusetts, and Bloomberg won only the caucuses in American Samoa. He announced Wednesday that he was dropping out of the race and endorsing Biden.
