The idea of a printed receipt with which the voter can prove how they voted is an excellent one, Carol.

Voting fraud is an old, old story in the USA as well as in many other countries. In the time of Tammany Hall, for instance, there were outrageous frauds perpetrated. First of all, people were bribed with drink and other inducements to vote for certain candidates favored by the ruling political machine in New York City at the time. On top of that, people were beaten and intimidated into not voting for other candidates. On top of that, the same individuals often voted several times, superficially altering their appearance by shaving off facial hair or wearing different clothes and then returning to vote AGAIN on the same day.

As time went by, of course, new laws were passed to make it more difficult to get away with such forms of fraud...so the fraud continued, but in some more clever or subtle fashion.

Is there voting fraud occurring now? You bet there is. Ways will be found, I assure you, because the stakes are very high, and it's all about money and power. Any system can be cheated by those who have the money and the will to cheat it...and there must be constant vigilance against that sort of thing.

Slits cut in the sides of ballot boxes? That's a dead giveaway. There's no way that a ballot box can be fully trusted if it has been compromised in that fashion.
