Non sequitur

From the debate in Wisconsin to require a photo ID for voting:

However, studies from Van Hollen’s office about past votes have found low percentages of voter fraud. In the 2004 presidential election, only 18 out of 3 million votes were fraudulent.
In other words: not having to show ID means it's hard to tell if people are committing voter fraud, but we know they're not, so no big deal! (The person making the statement does thing an ID requirement is a good idea, just not really necessary.)
