Yes, but the Board of Elections helps them vote. They may have their children fill out the ballot, or they may just pick a name that appeals to them. They can't be relied upon to vote Dem.
I do have a problem with letting people who haven't the foggiest notion who is President, or know anything about the current issues vote, but that's our system. I don't know how to fix it without also affecting younger people who just aren't aware. Sean Hannity did a bit a week or so ago where he was asking young people if they knew the Dem VP candidate, Stu Ped, and most said they did. The old folks vote as sensibly as these kids do.
"can't be relied upon to vote Dem"
They do vote DEM because the party workers are the ones signing them up .. and they do it by absentee ballott. They can control what party and who they vote for.
It's very nasty .. but when you're desperate for power .. you'll do anything.
