When I was a kid my parents told us children were not allowed inside the polling place. Gave it a serious, solemn air.
My dad would vote on the way home from work, then watch the kids while my mother went to vote.
A couple of elections as a kid, I made a few bucks passing out handbills outside the polls, and don't recall ever seeing a kid go inside with a voter. It just wasn't done.
I still think taking kids inside the polls is inappropriate. It's serious business, not a line to get a table at Golden Corral.
