Whatever Happened to the Gang of 14?

As a previous post noted, Majority Leader Reid recently exercised the "nuclear option" to end filibusters of most executive and judicial nominees.  In 2005, the prospect of such a move prompted a bipartisan group of senator -- The Gang of 14 -- to reach an agreement: the seven Democrats agreed not to block certain judicial nominees and the seven Republicans promised not to vote for the nuclear option.

Without the former, the Democratic minority could not sustain a filibuster.  Without the latter, the Republican majority could not pass the nuclear option.

So why did the Gang of 14 not re-emerge in 2013?  For one thing, nine of its members have left the Senate, either through death (Byrd, Inouye), retirement (Lieberman, Nelson, Warner, Snowe), appointment to other office (Salazar), or defeat (Chafee, DeWine).  Only the bolded names are left.
