Most countries have ID Cards for citizens like in Israel (Teudat Zehut). In the United States, most people think a driver's license is good enough. But what if you don't have a driver's license? I don't have a driver's license. I have a passport.
In the US, "it be racist" if you want people to have ID to vote. I don't think there is anything wrong with showing ID to vote or to prove who you are. In Israel everyone has to show ID to vote. You don't even have to register to vote in Israel. All citizens are sent a card in the mail telling them where to go to vote before each election.
