Bernard Sanders (born September 8, 1941) is an American politician who is the longest serving independent in U.S. congressional history and a member of the Democratic caucus. Sanders ran unsuccessfully for the 2016 Democratic nomination for president and is running again in 2020.
He isn't a democrat, but he is pulling the Democratic Candidates away from the winning path into the attractive socialist debate.
Since the Democrats want to beat Trump, then they going in any direction to do that.
The right path is to say what they are going to do for the American people, without taxing the people trillions of dollars.
