The clear answer: No. From Josh Marshall:
But here’s the key. This is fraud against ACORN. They end up paying people for registering more people than they actually signed up. If you register me three times to vote, the registrar will see two new registrations of an already registered person and the ones won’t count. If I successfully register Mickey Mouse to vote, on election day, Mickey Mouse will still be a cartoon character who cannot go to the local voting station and vote. Logically speaking there’s very little way a few phony names on the voting rolls could be used to commit actual vote fraud. And much more importantly, numerous studies and investigations have shown no evidence of anything more than a handful of isolated cases of actual instances of vote fraud.
