There are indications that Chambliss is coming around. The guy didn't call-in to Rush's show for feces and giggles. He heard loud and clear from the base, that they are unhappy with this ridiculous Gang of 10 crap. Even at the end of the discussion, Chambliss knew he was talking out of his ass and quietly realized he was in the wrong.
Since no vote has taken place yet, it's better to try and knock some sense into Chambliss (and the other 5 Republicans) rather than whining.
Whining? No, it's better to throw these idiots out just as soon as we possibly can. Why vote for any of them? They're not reliable and have shown their ignorance.
I heard Chambliss on Rush, and I certainly didn't sense him realizing anything. I just heard an arrogant a-hole arguing with Rush and spouting about "bipartisanship" and "getting something done.
Throw him out and let someone else have a go at it. A rat couldn't do any worse, and when they fail, it'll be a rat failure.
