Well, if you live in Miami-Dade County, Florida, you have to punch out a card, and make sure that you actually select the hole for the candidate you wish to elect. It doesn't sound too difficult, but it seems to have confused an awful lot of people.
But here on Caedes.net, all you have to do is click in the drop-down box next to the image, located underneath it's description. You then select a number from 1 (bad) to 10 (good), and click the "Vote" button next to it. Much easier, in my opinion.
