VERMONT WANTS TO INVESTIGATE O'KEEFE, NOT VOTER FRAUD
I've personally witnessed this type of activity in countless elections as well as other types of ballot tampering such as flooding the polls in small communities by university students who are watched by professors and absentee ballots filled out by nursing home workers, but most times when I challenged a ballot I lost the appeal because there "was no fraud intended." Even by the dead people who haven't missed an election in 120 years.
