And Democratic Senator Sheldon Whitehouse of Rhode Island has introduced a Senate bill that would outlaw voter caging. “Caging” is an election suppression tactic that seeks to bar voters by challenging their eligibility to vote. Republicans have been accused of maintaining caging lists skewed toward people of color, predominantly African Americans. The Caging Prohibition Act would prohibit challenges to a person’s eligibility based solely on returned mail or a caging list. The bill would also penalize anyone who challenges another voter’s eligibility without sufficient evidence.
