I can't find any verification about the absentee ballot stuff on Snopes, but I'm going to keep looking. However, the bit about 'passive electioneering' is at least partially true depending on where you live:

Please be very careful with that - watch your t-shirts, bags, hats, pins, whatever when you go in to the polling station for anything that could be considered partisan. Something that small may slide in some districts, but it's better to be safe than sorry and get a chance to vote.
