The poll isn’t even a little bit scientific. Reading anything into the results is utter hogwash. Sanders is up probably because someone created a script to vote continuously through the night.
You are right, I am sure. I refreshed my screen twice; Trump and Sanders were both up about 200 votes in 15 seconds.
Rubio went up 7 votes, most others, none.
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.
