At some point soon in the future the Democratic establishment along with the White House had better figure out that stuff like this is what is going to give the Republicans back the House and possibly the Senate if its allowed to keep happening. Right now we are allowing a small group of Republican light members of Congress to bring all of our legislation so far to the right as to not resemble mainstream Democratic thought. And I can promise you that those select few won't be the ones who really catch hell behind it, it will be the overwhelming majority of elected Democrats who rely on their base to come out in big numbers to vote for them in midterm elections. I truly believe that New Dems, ConservaDems and Blue Dogs wouldn't really mind if the Republicans took over Congress again so long as they keep getting money from their corporatist backers.
If somebody doesn't reign them in soon and stop "compromising" with them on issues that should amount to common sense and DEFINITELY amount to mainstream Democratic thought, we really will have a blood bath next year, no matter how bad the GOP screws themselves. When these folks start getting threatened of being stripped of seniority and or chairmanships then we will see how beholden they are to special interests. Until that day you can expect to see more of this kind of obstruction within our own party.
It is what it is.
