At a rally in Florida President Trump endorsed requiring those who would vote to show a government-issued photo identification, in most cases a driver's license or passport. Photo ID cards are available for non-drivers, at reasonable cost in most states, from the DMV.
COTTonLINE writes to support making this a requirement in federal elections. If states wish to waive the requirement in local elections, I have no objection. If they wish to make ID cards available free to the poor, that's okay too.
The DrsC agree neither of us would be offended at being asked to show proof of identity to vote. We show ID every time we board a plane, or cash a check, or embark on a cruise ship. Voting is important and evidence suggests voting fraud is not uncommon, if sometimes inadvertent.
