What these comparisons show is that there are discrepancies between exit polls and vote counts by computer. The question is why do these discrepancies always favor the DNC? If the discrepancies were random, then the comparison between Sanders and Biden would be random. But they are not random. The DNC’s candidate always gains in the counting. And that is highly suspicious.
Not only have exit polls been way off, but Bernie Sanders has won every single caucus state where votes are hand-counted except one: Iowa, Nevada, and North Dakota. American Samoa is the only caucus Bernie didn’t win; fellow progressive Tulsi Gabbard won the territory.
