At a Monday rally in East Los Angeles ahead of the June 7 California primary, the Vermont senator cited an NBC News/Wall Street Journal poll released over the weekend that showed the margin between Democratic front-runner Hillary ClintonHillary Diane Rodham ClintonState cites 38 people for violations in Clinton email review Trump campaign to hold rallies in Mississippi, Kentucky Biden struggles to reverse fall MORE and Trump narrowing to 3 points. The same survey showed Sanders beating Trump by a 15-point margin in a hypothetical match-up, 54 percent to 39 percent

Sanders said Democrats at the convention in Philadelphia this July should take a “hard look” based on that poll’s findings. Sanders frequently touts polls that show him with a larger lead than Clinton in hypothetical match-ups with Trump.

“If the Democrats want to be absolutely certain, as we must be, that Donald Trump never becomes president, then our campaign is the strongest campaign,” Sanders said.

He expressed confidence he’ll claim victory in the delegate-rich primary, thanks to numerous rallies throughout the state and an “unprecedented level” of new voters registering ahead of the Monday deadline. Sanders supporters have also filed a federal lawsuit asking that voter registration be extended until June 7, the day of the primary.

“That’s what our campaign is about -- a grassroots campaign, not a fancy campaign and we’re going to talk to people of California about the issues of concern in this state and United States of America,” he said.

Sanders has previously acknowledged that he has an uphill battle in winning the nomination. Clinton is 90 delegates short of the 2383 needed, while Sanders needs almost 850 delegates to clinch the nomination, according an Associated Press tally. Despite Clinton's lead, Sanders has vowed to remain in the race and keep fighting for delegates.

On Monday, his campaign got to choose one-third of the seats on the committee that writes the party’s platform. The increased representation on that convention committee will help him shape the party's platform to align with his own progressive politics, such as setting the minimum wage at $15.
