If you've ever seen a movie in which a boat is caught in a storm. At first the waves are distant and the crew ignores them. Then suddenly the storm has swept in and everyone is running for cover, doing anything they can to prepare for a storm that's already here.
And that's the left wing of the Democratic party right now, too slow to recognize the storm because of its media cocoon and now rushing to throw anything they can at it, from voter fraud to scandals and smears.
