This report by CBS 2 in California is exactly the reason why Voter ID was passed by so many legislatures around the country. They found hundreds of people voting even though they are dead!
This is blatant voter fraud, and you know this is going on all around the country. Just as CBS 2 points out, they have no way of knowing how these people voted. Which is why the only way this kind of voter fraud can be stopped is through Voter ID.
This is also why Democrats are so opposed to Voter ID. They claim it disenfranchises voters, but in reality the only thing it disenfranchises is their ability to cheat.
