"As Mike has traversed the country, meeting with voters in more than 70 cities across 27 states, he’s engaged with voters about his record of taking on tough fights on the issues that matter most to Americans.

"Tonight, only one-third of delegates will be allotted. As Mike said tonight, 'No matter how many delegates we win tonight, we have done something no one else thought was possible. In just three months, we've gone from just 1% in the polls to being a contender for the Democratic nomination.'
