This chart is from the Public Religion Research Institute. It's not really surprising. It shows that while Republicans worry about voter fraud (which is virtually non-existent), Democrats are much more worried about voters being disenfranchised (which is actually happening -- using voter fraud as an excuse). The general public and Independents both have pluralities worrying more about disenfranchisement than fraud.
