The Left's last argument for the Senate health care bill

Here's Jason Rosenhouse's take on why the Senate health care bill should be supported by the Left. He's essentially saying that he supports the bill because, hey, if you want to make an omelette, you must be willing to break a few eggs:

So what about the question in the title of this post[Should the Bill be Killed?] My answer is no. In the end, as awful as this bill is, I have to side with Krugman and Reich. The argument I find most convincing is that you have to pass something to get your foot in the door for future reforms. If the bill dies, that is it for health care reform for a good long time. Pass the bill, which does do some good things along with its more deplorable parts, and you establish the basic idea of universal health insurance. It will be pretty hard for future Republican majorities to take it away.
