I think the spreads will get tighter as we get closer to the election. As you said, the election is still over 2 years away and there will be more interest in it as time goes on. You could put up a bid or offer for an amount in between what is available and it might get filled. For example: Buy Rand Paul at 0.99.
the 2014 election shares are up, and there's still a big disparity between buy and sell. i too am thinking that with more volume, the gap between buy and sell will close. but as it stands, there is no point in buying and not letting your shares expire.
