It is insane that Democratic candidates are dropping out of races as a result of reading fake polls on twitter. If their candidacy could be destroyed by that, it shouldn't have been started in the first place. Also, typical authoritarian solution to try to figure out how to eliminate or prosecute fake polls, rather than to end the substitution of triangulation for belief. It would be wonderful if someone could believe in something other than winning. You might win; people are starved for candidates who believe in something other than personal enrichment.
You can't libel the general public. I can lie about whatever poll I want, as long as I'm not selling you anything (which would be fraud.) Politicians can't be prosecuted for the promises they made during the campaign that they immediately abandoned after being elected, but I, a random citizen, am held to a higher standard about my pronouncements of the opinions of the randomly chosen and race-weighted public? Get out of here...
