Check out this post from Josh Marshall about the split in the Senate "Centrist Coalition" and the birth of the new "Bipartisan Members Group".  Before you ask, yep, Joe Lieberman was involved.  This almost begs the question what does it take for the body's leading "political party of one" to get even more notice in the press and did he clear this with Party Chair, John Orman?  Better yet, who knew that "Centrists" could be so fractious?
