Ezra Klein says Sen. Joe Lieberman's most recent ultimatum on the health care reform bill is all about avenging his loss in the 2006 Democratic primary.
"To put this in context, Lieberman was invited to participate in the process that led to the Medicare buy-in. His opposition would have killed it before liberals invested in the idea. Instead, he skipped the meetings and is forcing liberals to give up yet another compromise. Each time he does that, he increases the chances of the bill's failure that much more. And if there's a policy rationale here, it's not apparent to me, or to others who've interviewed him. At this point, Lieberman seems primarily motivated by torturing liberals. That is to say, he seems willing to cause the deaths of hundreds of thousands of people in order to settle an old electoral score."
