It's easy... Assume that John Harold Slomski, democrat at large, registers in his 3rd precinct under his real name and he votes there in person on Nov 2.
But he also registers as:
John Slomski
John Slomsky
Jon Slomski
Jon Slomsky
John Harold Slomski
Jon Harold Slomski
John H. Slomski
Jon H. Slomski
And the variations go on, and on, and on......
And he votes all of those alias's via absentee ballot?
Possible? Maybe.....
How about a very public proclamation by some government figures, reminding everyone of the jail time and fines associated with voter fraud, and that the state, local and federal agencies will be pursuing this vigorously. Scare the hell out of anyone who is planning to do this, and then follow up on it (unlike the non-follow up that took place after 2000, when everyone on Free Republic predicted this was going to happen 4 years hence).
what ID is required in the various states. in NJ I had to show a utility bill with my name and address.
Possible? Maybe.....
Possible, and likely. And, even if he doesn't vote all the alias's, there are plenty of unsupervised democratically-controlled pricincts that will vote "on his behalf" at closing time.
