My colleagues already have commented on this, but I say we give the Democrats what they are asking for on this one: Vote when you are 21 or older, disenfranchise felons and some violent misdemeanor offenders, pass a background check, and show an ID that is verified through a law-enforcement database at the polls.
Also, go to jail if you try to fake your way through any part of the process.
At last, there will be parity!
