Sen. Bernie Sanders lost big to front-runner Hillary Clinton Tuesday night, making it all but impossible for him to catch up in the Democratic presidential race. Clinton celebrated double-digit victories in the delegate-rich states of Florida, North Carolina and Ohio as well as a narrow win in Illinois. The race in Missouri was still too close to call Wednesday morning, but the former secretary of state led Sanders by more than 1,500 votes with 99 percent of precincts reporting in the state’s primary, according to Fox News.

“This was another Super Tuesday for our campaign,” Clinton said at a victory party in West Palm Beach, Florida. “We are very close to winning the Democratic Party nomination and winning the election in November.”

Despite Tuesday’s losses, Sanders gave no indication that he would call it quits on his 2016 presidential bid. The Vermont senator had hoped for another upset win in the hard-fought Ohio primary, like the one he scored with Rust Belt voters in Michigan last week. Here’s a breakdown of who has won which states and how many delegates so far ahead of next week’s contests in Arizona, Idaho and Utah:

Clinton is ahead with 1,084 delegates, along with an enormous superdelegate lead. She has won contests in Iowa, Nevada, South Carolina, Alabama, Arkansas, Georgia, Massachusetts, Tennessee, Texas, Virginia, Louisiana, Mississippi, Florida, Illinois, North Carolina and Ohio as well as the American Samoa and Northern Mariana Islands caucuses, according to a tally published by  the Wall Street Journal.

Meanwhile, Sanders is trailing with 774 delegates. The self-described democratic socialist has won contests in New Hampshire, Colorado, Minnesota, Oklahoma, Vermont, Kansas, Nebraska, Maine and most recently Michigan. Sanders would have to win 58 percent of the remaining pledged delegates to catch up. In other words, he needs to win just about every remaining state by considerable margins to beat Clinton, Vox News reported.
