They decided to stick with Sen. Tom Coburn, who has personally blocked 80 bills in the Senate using holds that prevent unanimous consent. So today, Sen. Harry Reid brought up a bunch of those bills together, and most of Coburn's GOP allies refused to let the Senate vote on these measures, even though it kills some of the legislation they sponsored and supported.
Why? Because they have successfully used the filibuster to try and paint Democrats as ineffective. So, they are willing to let kids and sick people suffer in order to score cheap political points.
