The First Tuesday in June
ADDENDUM: The memsahib and I did actually wander down to our local polling place and made the requisite marks on the ballot card. Which the official ballot counting machine proceeded to reject. The Voting Place Guy tried to process mine six times before apologizing and putting it in the official electoral plastic tub underneath the official ballot counting machine. Same thing with Mary and with the fellow who voted before us. And apparently more than a few others. It seems to be happening all over this area. Is it incompetence or election fraud? Couldn't tell you. In the long run, though, in this area it only matters if you're a Democrat. Whoever gets the Democrat nomination will get an elected office. If you're a Republican all you're going to get is the opportunity to put on your resumé that you were the Republican nominee for senate or congress or whatever . . . and got squashed like a bug.
(The Voting Place Guy probably does have a more impressive title than Voting Place Guy but I don't know what it might be.)
