Well, we SHOULD. In addition, voting by mail should be outlawed except for carefully monitored exceptions such as military members serving outside their home states, and all voters should be required to display a government-issued, biometric ID when they show up to vote.
5,000 illegals, most of whom would vote Democrat, apparently made the difference in a number of close votes in Colorado last November. Makes me furious.
Early voting is most likely rife with corruption as well.
