It's not intended to be a statement saying he will confirm, it is a statement saying that the process will go forward. It is a rebuke of David Frum and his asinine petition. IOW's Miers will get her hearing and the senate will offer consent or not. As it should be, absent the stake, the fire and the mob.
Having reread the original post, I concede you are correct. The quotes were caveated with the header that they concerned the hearings. The implication is that not all of those quoted are on record as supporting her nomination (although interestingly, two staunch conservatives are already onboard).
