I think their results for Trump vs. Sanders are total BS other than the fact that they probably polled people who would vote for ANY left-winger. I talk to people all the time, and even though Bernie Sanders is drawing some decent crowds it seems like most people don’t have any idea who he is.
In 1980 Ronald Reagan was losing to Jimmy Carter til the day they counted the votes
The largest crowd for Dems or the GOP (drawn so far) is the one is Phoenix, in which Sanders drew more than 11,000 people.
In another town, albeit a very small town (40,000 people), Sanders drew 1/8 of the total population to his event. No one on either side has equaled that percentage yet.
One good thing that can be said about him is that he can pull in the numbers for a speech.
