It's not over 'til it's over.

There's more to the primaries than picking the nominee. The delegates to the convention will write, amend and approve the party platform. Speeches will be made to the nation in prime time. The party chair will be chosen and DNC positions filled. Whether the nominee is Bernie Sanders or Hillary Clinton, the more progressives that are elected to the convention, the more likely that the Democratic Party will return to its historic role as the champion of social and economic equality.
