They should take that machine out of service and use paper ballots. This is one type of fraud expected.
Other forms of electronic fraud are described in the links above post #1.
If anyone should witness electronic fraud and the election official does not remedy or act to stop the fraud, call the police! Don’t mess around. Demand paper ballots only!
I just got a 2nd hand report that machines are not working in So Utah—near St George—and they had to switch to paper ballots. Hope they have enough of those on hand-—I expect a very large turnout.
