Rumor vs Reality

Ballot collecting helps people who are poor, elderly, or live far from a post office to return their mail-in ballots. After completing and sealing their ballot, the voter hands it to another person to submit at an official drop-off location. This process is legal in 26 states. It is especially helpful for Native Americans.
The rules for ballot gathering are very strict. To date, the only charges of ballot harvesting fraud resulted from a North Carolina congressional race in 2018. There, a GOP operative was indicted for gathering and completing hundreds of ballots. A recent video claiming ballot harvesting fraud in Minnesota was the product of a “coordinated disinformation campaign,” according to researchers at Stanford University.
