The Democratic leadership blew this one in a huge way. Hiding under the bed on this was just unbelievably stupid and reinforced the worst stereotypes of Dems as weak and standing for nothing.
What hurts the most is not that we lost the Geneva Conventions battle, it's that we lost it because our leaders froze up and wet themselves, even though we wanted them to fight and would have supported them to the hilt if they had.
I don't think there's anything more to say by way of a post mortem.
Looking forward, it's hugely important that Democrats win back the House, at a minimum. Even when the leadership gets rolled in the most embarassing way, rank and file Democrats need to stay motivated to win this thing. There are massive differences between Democrats and Republicans. For starters, Republicans want to stay in Iraq, bomb Iran and transform America into a police state.
