More amusing is the Dominion IS DEIBOLD. The fascist left loves to say "Deibold bad, Dominion good, bahh, bahhh." But Deibold simply merged with other concerns and rebranded to Dominion - that the left now says are flawless and perfect.
The number 1 form of election fraud is proxy voting. An illegal alien voting using the registration of dead voters or voters who have moved. It is impossible to prove on a large scale and can only be stopped through clean registration rolls and voter ID - which is why the democrats fight with everything they have to stop both ID and cleaning voter rolls.
The second most common is the "midnight dump"
