There's already evidence of plenty:
1. On-going investigation re Indian absentee ballots
2. Signatures on absentee ballots looking obviously identical
3. Extending poll times in middle of election
4. TO BE YET DISCOVERED
Seems to me that every absentee ballot should be checked against every application signature.
Furthermore, she (the vote fraud woman) has two completely different sounding names. How can we be sure that the same person on these reservations was not voting as Mary Smith, Maria Redfeather, and Maya Featherred? Are Indians who live on reservations even given social security numbers? Do they have to register for the draft and pay taxes? And, if there was fraud, would the fact that it was on a reservation (federal land?) make the punishment more severe?
