It is very clever of the people committing voter registration fraud to make charges against the people who are trying to do the job honestly.
Of course ACORN has had allegations of voter fraud lodged against them in 12 states. It is the Republicans who are lodging the allegations. It is one thing to make an allegation. It is quite another thing to prove it. Trying to use the number of allegations as proof of any one of them takes a lot of gall coming from the ones lodging the frivolous allegations in order to cover their own tracks.
