Bernie Sanders conceded the Democratic Presidential nomination to Hillary Clinton this morning and said he intends to do everything he can to make certain she defeats Donald Trump.

Now, the question is whether Sanders enthusiastic supporters will show up to vote in November, and whether Clinton will be their Plan B.
