I wondered that too. Interesting how that tidbit was omitted from the story.
Once a vote is cast there is not link between the voter and the ballot. That's the nature of a secret ballot, so we'll never really know how many of the fraudulent votes went for which candidates. But given the democRATs courting of the felon vote, and the high percentage of inner city precincts associated with the fraudulent ballots, I'd place the percentage of fraudulent votes at about 99.9% democRAT.
