Riggs: "Sanders is confident in his message, and unlike so many Dems, defends his point rabidly. I happen to like Obama, but I think he is lazy with the bully pulpit. Sanders is rocking the boat by actually grabbing the gunnels and pulling. Mainstream Dems have been rocking the boat by telling folks a wind and a tide are about to show up at any moment. Same goes for Trump. Clinton knew how to fight as well."
Question: Does Bernie Sanders pose a serious Democratic primary challenge to Hillary Clinton? Why is he attractive to so many?
