the criticism of Bushco DeLay could just be going passive aggressive on them.
His not squelching this mini-rebellion could be a message of sorts.
But I see it more as an expression of the downside of walking in lockstep. It's often a strength but but when people break ranks it can get extra nasty.
Seeing such internecine warfare is something of a holy grail amongst us of the rebel alliance. :)
Frank Herbert, of Dune fame, had a nice quote. While not totally apropos to this particular situation it does underscore one key weakness of Bushco that will, in part, lead to their undoing.
http://www.generationterrorists.com/quotes/dune.shtml"When religion and politics travel in the same cart, the riders believe nothing can stand in their way. Their movement becomes headlong - faster and faster and faster. they put aside all thoughts of obstacles and forget that a precipice does not show itself to the man in a bland rush until it's too late."
