The Coup of 2011 —  It occurred to me today that there’s at least some chance that in January of 2011 the US Senate will have 49 Democrats, Joe Lieberman, Charlie Crist, and 49 Republicans.  Which is to say that Lieberman & Crist could form a two-man caucus, hold the balance of power, and drive organization of the Senate.
