I wouldn’t assume it was some script. It’s conviction and enthusiasm. Some blog that communists lurk in probably mentioned the poll.
Hillary voters have no convictions or principles. No enthusiasm. She’s a greedy old fart. Sanders supporters are enthusiastically hell bent on destroying the USA. They hate it.
Sanders had a few 1000 votes last night at 8pm CDT. This morning he has over 340,000. Assuming a 12 hour cycle that is over 7 votes per second all night long. I’m rounding down on the votes and rounding up on the time, so the real number is lager than this.
