The 11 did not "break ranks". It had been decided by Reid and the Dem caucus that is was O.K. for these to vote "for" because it would not change the outcome. I suspect (but haven't looked it up) that these 11 are running for re-election in most cases and they need the voters in their state. Reid is/was aware of this so they were told to go ahead and vote for it.
Exactly. It was all Kabuki, cover for rats.
