I think Mittons will do the right thing.
hmm. if this is accurate, having two committed nos off the bat would actually make confirmation slightly difficult. the arizona election is a special election, so kelly could take office as early as the end of november. and collins will be under huge pressure to pledge to not confirm during a lame duck. of course, if she loses, there's no reason she has to keep her pledge (and she'll also be under huge pressure to confirm).
grassley has also made anti-confirmation noises in the past, and since he's older than balls, he has no reelection (or post-senate employment) pressure.
