Care to share where you got the demo ballot from? Is it at the polls or online? I have a Ballot Sample which I got online after entering my voter info, not sure if this is what you're referring to.
EDIT:
If you don't know who to vote for and want to be prepared, you can get a Sample Ballot online. You enter your address and chose either Rep. or Dem. Ballot and on it you will have everyone you can vote for. Be prepared!
