This has been for the last week, CYA.
Yep, it's been about a bunch of experienced, mainstream congresscritters scared of having their re-elections challenged by a freshman lunatic fringe who wouldn't know governance if you shoved it up their...noses. The old dogs are just trying to make a good show, pin any and all compromise (you know...the thing that actually gets things done?) on the opposition, and get a deal done before the grenade goes off in their pants.
It's a very, very dangerous, self-serving game -- on the part of the veterans. I suspect the newly-elected radicals actually believe in what they're doing. Their crime is ignorance. Ours is electing them. A more informed electorate would rise up and sweep them out en masse at the next opportunity, but we are a largely uninformed electorate with a very short memory.
