Unfortunately, this doesn't derail what I think McConnell's real agenda is: packing the federal judiciary with young right-wing lunatics. Unlike on health care, where he lost Collins, Murkowski, and McCain, and on taxes, where he's already lost Corker and now could lose someone like Heller who sees his seat being under serious threat, and might be willing to draw the ire of the donors if it allows him to keep his voters (he wouldn't have flipped when doing so pushed it from 51 to 50 plus Pence, because then it's a futile gesture), he's held his caucus on judgeships, and he can keep ramming them through with 51 votes as well as with 52.
Of course, there's also the danger that Robert Menendez will be convicted before Chris Christie leaves office, which would put the GOP back at 52 in the Senate, at least for a time.
