Story highlights Clinton currently has 2,313 total delegates is expected to clinch the nomination in the next few days

Sanders says he can still woo enough of her superdelegates between now and the Democratic convention

Washington (CNN) Vermont Sen. Bernie Sanders on Saturday vowed to continue his fight for the Democratic nomination beyond the primary season, telling reporters at a news conference in Los Angeles that he plans to go after Hillary Clinton's superdelegates.

Clinton currently has 2,313 total delegates -- 1,769 of which are pledged and 544 of which are superdelegates -- and she is expected to cross the 2,383-delgate threshold in the next few days to clinch the nomination. But Sanders, who has 1,501 pledged delegates and only 46 superdelegates, says he can still woo enough of her superdelegates between now and the Democratic convention in July to swing the nomination his way.

It's a tall order.

Pledged delegates emerge from primaries and caucuses, while superdelegates are party leaders -- elected officials and former ones who have individually committed to a candidate. It would be unprecedented for the number of superdelegates Sanders needs to switch allegiances, and, like Clinton this year, then-Sen. Barack Obama entered the 2008 convention without a majority of pledged delegates.

Sanders is making this pledge to keep his fight alive in the closing days of the California primary campaign, sending a signal to his supporters that the race isn't finished.
