I can think of one difference between our two choices for this year that I haven't seen mentioned in this thread and it's the choice that each would make to fill probable soon to be empty Supreme Court Justice seats. We've seen what Obama likes to nominate, and I beleive it's very easy to beleive that Mitt would nominate someone much more conservative. If Obama wins and does indeed to place two more justices on the Supreme Court, well, that'll be about the last nail in the coffin for this country.
