"Evan Bayh Organizing Senate Version of “Blue Dog” Caucus"
This seems like a good idea to me. With Republicans out of power, the GOP can’t really block progressive change in exchange for large sums of special interest money. That creates an important market niche for Democrats willing to do the work. It was a good racket for the House Blue Dogs in 2007-2008 and there’s no reason it couldn’t work for Senate analogues over the next couple of years.
