Just like the healthcare debate, the Republicans aren't willing to destroy the whole legislating system to stop a financial regulation bill they don't like, but it looks like they are willing to play politics with the health of Senator Byrd, and delay the issue.
If the Republicans or any group of Senators were willing to do whatever it took to stop a bill, fine. But in the end, the bill will be passed. Maybe it will get changed somewhat, but not much. So why not be cordial, and not demand a 60 vote cloture standard?
There needs to be a limit to politics.
Again, if they really think something is bad for America, and they pull out all the stops, I support that. That is how our system should work.
But this is posturing. And there should be rules in that case.
