Sanders' problem: To win, he needs Clinton's superdelegates

Remember those superdelegates, the Democratic Party leaders and elected officials who can vote for the candidate of their choice?

On Saturday, Sanders netted more than two dozen delegates over Clinton in Washington state after the party released vote data broken down by congressional district.

Clinton won the Guam caucus on Saturday and how needs just 17 percent of the delegates at stake in upcoming contests to clinch the nomination.

The totals include delegates won in primaries and caucuses, as well as public endorsements from superdelegates.

Early in the campaign, Sanders said his plan was to win a majority of pledged delegates, which would persuade the superdelegates to support him as well.

If she can instead pull out solid victories this month in West Virginia, Kentucky and Oregon — and get some additional endorsements from superdelegates — Clinton could end up celebrating as a presumptive nominee in a place in need of some financial attention:

Clinton has recently sent advisers to Puerto Rico to learn more about the Zika virus and called on Congress to assist with the island's financial crisis.

Sanders' steep path to 2,383 can only really end at the party's convention in Philadelphia, where he intends to give superdelegates all his attention and make the case he is the better general election candidate.
