Bernie is irreverent, this is about the revolution.

He is about pushing the Overton window to the left, much faster than what would normally occur.

McGovern got crushed by Nixon, yet many of the policies espoused by McGovern ended up being pushed by Nixon, and subsequent generations of democrats now are far to the left of his ideas, as well as Republicans

Bernie is doing what the revolution demands, which has nothing to do with him defeating Trump.

Now i don't think it's impossible Bernie couldn't win, but more of the masses must be made to accept and endorse these ideas even if its only through silence. And make no mistake, as is stated at the end of this ad, the revolution has begun.
