Both Canada and the United Kingdom require some form of identification in order to vote in all elections. Democrats call such requirements racist.
Canada and the UK require a drivers license to vote, or at least two other forms of ID to prove that the person voting is who they say they are. In the United States, some states allow for a mail in ballot without any form of ID being shown. America should mandate some form of identification any time a person votes, just like these two other advanced nations.
