The late David Rosenbaum's last article: his obituary for Lloyd Bentsen. It's good.
I would disagree with Rosenbaum's claim that Bentsen's "Senate career was not particularly distinguished." I don't believe that either the 1990 or the 1993 deficit-reduction bill would have made it off the runway without him first as Finance Committee chair and second as Treasury Secretary. That is, I think, an enormous accomplishment--albeit one that the Bushies have managed to erase.
