Because they were the only ones who were informed enough to have their ID's out and ready to go!

If it's like my polling place, the signs that read "Have Proper ID Ready" would have pointed out the DUmmies, who would either wait until the last second to search for it (like the DUmbass who writes a check in the express lane), or bitch LOUDLY that this was an "infringement" on their voting rights. (We also break down the crowd into several lines, according to your last name. I'm sure the DUmmies f'ed that up, too.)
Last November, someone tried that "speech" at my precinct, and the poll worker told him if he didn't have it, or wouldn't show it, to get the hell out! This guy was apparently new to the area, because we have had to show ID to vote in Virginia since...FOREVER!!!!
I wonder if any DUmmies have to show ID to vote for
