Everything you wanted to know about Buffy the Vampire Slayer, from the wonderful Wikipedia. (I stumbled on this trying to remember if War of the Worlds was originally broadcast on Halloween, but it was actually October 30th, 1938.)
Here’s an idea I saw over at Idea a Day, where ideas are free:
Allow voters in a political election to cast a vote against a candidate. Voters would still only get one vote, but each “against” vote would nullify a “for” vote.
I think this might help.
