That message is you can't have it all!" he said at the event.Actress Sarah Silverman also appeared at the event to give her endorsement."Bernie is not for sale!" she said.Former U.S. Secretary of State Hillary Clinton is still considered the front runner, but Sanders' supporters say the huge crowds for his events shows the senator shouldn't be counted out.On Saturday in Seattle, 15,000 attended his rally.
