Vermont U.S. Sen. Bernie Sanders showed his campaign still has signs of life on Tuesday, as he notched four wins against rival Hillary Clinton. The former U.S. Secretary of State, however, closed out the night the clear victor, winning seven states.

Sanders is projected to win the Minnesota and Colorado Democratic caucuses, as well as the Oklahoma and Vermont primaries, according to NBC News. "We want to win in every part of the country, that goes without saying, but it does say something and it means so much to me that the people who know me best, ... have voted so strongly to put us in the White House," he said in a speech. With 46 percent of the vote in, Sanders led Clinton 58 to percent to 41 percent in Colorado, according to NBC News. In Minnesota, Sanders led Clinton 59 percent to 41 percent with 41 percent of the vote in.

Clinton, though, is strongly positioned heading into the next big Democratic contests in Ohio and Florida, two traditional swing states, scheduled to hold their primaries on March 15. Clinton is the projected winner in Texas, Virginia, Georgia, Alabama, Tennessee, Arkansas and Massachusetts, NBC News said. The race in Massachusetts was neck and neck, with Sanders having led his rival at one point. Clinton was leading Sanders in Massachusetts entering Super Tuesday, according to recent polls. Exit poll data from NBC News showed Sanders leading Clinton among white voters in Massachusetts. Eighty-six percent of voters in that state identified themselves as white. Over 80 percent of voters in the state also said they believe Sanders is honest and trustworthy, while 53 percent said they felt the same way about Clinton.

Clinton, however, is the projected winner in the three Democratic contests offering the most amount of delegates. Exit poll data from NBC showed 73 percent of people age 45 and over in Texas said they voted for Clinton. Fifty-seven percent of voters in Texas said they were at least 45 years old. "All across our country today, Democrats voted to break down barriers so we can all rise together," Clinton said in a speech.
