Remember those superdelegates, the Democratic Party leaders and elected officials who can vote for the candidate of their choice? The ones Sanders' supporters have been complaining about for months? It turns out, to have a shot at beating out Hillary Clinton for the Democratic nomination for president, he needs them.
A lot of them.
He needs the ones who remain uncommitted, as well as more than 200 of those who have already publicly endorsed Clinton. Mathematically, Sanders cannot win the nomination without that support.
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.
