If you have to be a U.S. citizen to vote and ID is required to register, and you receiver a voter registration card, then what is wrong with asking for THE VOTER REGISTRATION card to be presented when voting? I don't expect an answer, it was a rhetorical question.
According to the liberal way of thinking, it is wrong to ask for ID when voting. Therefore, it is wrong to ask for ID when purchasing liquor, prescription drugs, welfare checks and food stamps and airline tickets when flying. Heck, it must be wrong to ask for a passport when traveling in and out of the country.

It's racist to ask, because everyone knows that minorities don't have ID.
