In general, these questions would benefit from more nuance, as "yes/no" don't accurately portray each candidate's position on a bunch of different issues. Some examples:

- Romney believes the right to abortion ought to be preserved in cases of rape or when there's a threat to the mother's life. - Obama hasn't endorsed raising the Social Security retirement age and campaigned against in 2008, but seemed willing to consider the idea as part of a compromise solvency package during the Bowles-Simpson negotiations. - Obama flat out supports lowering the corporate tax rate.

Also, when someone lands in the middle zone, it doesn't really make sense to say they should vote for a 3rd party as virtually all 3rd party candidates are either to the left of Obama or the right of Romney.
