Saw the film and it never accused any political party. It carefully documented the ballot stuffers using cell phone pings with a system that was purchased legally. The "mules" traveled from pick up points to hundreds of ballot boxes between the hours of 12AM and 5 AM. You can judge for yourself who drops off 10 or more ballots in the middle of the night.
Everyone needs to see how it was done and decide for themselves if this is right or an operation of organized crime.
