The whole idea is that the unions/Democrats will make sure these registered voters participate - whether they know they've participated or not.   The gold standard for vote fraud is the registered voter who no longer lives in the jurisdiction followed by the registered voter who doesn't vote.   Early voting, easy absentee voting, direct or phone contact, and poll watching enables interest groups to determine who has not voted and who is registered but no longer in the district.   Then they can just go vote for them either by absentee, in person, or where allowed by mail.   And before some lefty chimes in that there is no evidence of voter fraud, that's because most of it is in the Democrat controlled places and nobody is looking for voter fraud; its a feature, not a bug, which allows the city vote to overwhelm the suburban/rural vote.
