Democratic presidential hopeful Bernie Sanders made an eleventh-hour push for the nomination Monday night in San Francisco, despite reports earlier in the evening that his opponent, Hillary Clinton, had clinched the necessary number of delegates.
Sanders energized thousands at Crissy Field, telling supporters he needs results at the polls Tuesday.
Earlier Monday, NBC declared Clinton the presumptive nominee based on the delegate and superdelegate counts.
"It's going to be difficult," Sanders said. "I'm not going to deny that for a second."
But the Vermont senator was not giving up, saying superdelegates don't officially vote until July, which gives him time to possiibly change some of those votes.
"According to all the state polls and according to all the national polls that I've seen, Bernie Sanders is a much stronger candidate against Donald Trump," Sanders said.
Meanwhile, Clinton, campaigning in Los Angeles, wasn't celebrating just yet.

"We're on the brink of a historic, unprecedented moment, but we still have work to do," she said.
Back in San Francisco, Sanders supporters believe, win or lose, their candidate's tireless energy and refusal to give in will ultimately create the change they're looking for.
"I will write Bernie Sanders in," supporter Ricky Molina said. "It's Bernie or bust."
