And then there was Bernie sanders. Will the real Bernie sanders please stand up. Wait a second! I am so sick of the 1% getting this preferential treatment. Reporter: Sanders and Larry David side by side on "Snl" overnight. Sounds like socialism to me. Democratic socialism. What's the difference? Huge difference.

I feel like a rock 'N' roll star. Reporter: Earlier in the day, sanders rallying supporters in New Hampshire. We went to Iowa, 40 or 50 points down in the polls. We end up getting a virtual tie.
