Story highlights Bernie Sanders must win 2,383 delegates but only 933 delegates remain

The Vermont senator's aides see a path to the nomination through a convention battle in Philadelphia

Washington (CNN) It is mathematically impossible for Bernie Sanders to win enough delegates in the remaining Democratic contests to secure the nomination, but his aides see a path through a convention battle in Philadelphia that would target the party's superdelegates.

The Democratic nominee must win 2,383 delegates to secure the nomination, but with only 933 delegates up for grabs in the remaining contests, it is impossible for Sanders to get there just by winning contests against front-runner Hillary Clinton. The Vermont senator has racked up 1,444 delegates, according to the latest CNN delegate tally, but would need to win more than 100% of the remaining delegates.

Asked about this hurdle Wednesday, Sanders campaign manager Jeff Weaver dismissed it.

"The truth is, no one is going to the convention with the requisite number of pledged delegates to win. The superdelegates are going to decide this race," Weaver said on CNN's "New Day."

The comment wasn't as much a guarantee as a promise from the Sanders camp that they would fight Clinton all the way to Philadelphia with the hopes of putting her in the same boat as them, fighting over superdelegates.
