Better idea: Issue every American citizen, at no out of pocket cost to him or her, a US passport. Update it periodically. Require voters to show their passport at the polls.
Problem solved.
issue every American a good quality firearm of his or her choice, the price being only that they complete a firearms safety class.
this will solve 90 percent of the problem.
also restore sbooting sports and firearms safety classes to all high schools. toss out ethnic grievance studies to pay for the costs
