Matt Yglesias nails the "double-crossing" Lieberman:
The leverage that Lieberman and other “centrists” have obtained on this issue (and on climate change) stems from a demonstrated willingness to embrace sociopathic indifference to the human cost of their actions.
That's exactly effing right. He's playing politics while people are dying. The rest of us are rolling the dice every day, or filing bankruptcy due to medical bills, or lining up for free clinics. Upwards of 3,000 deaths per month due to a lack of health insurance and Joe Lieberman is still stopping off for Jujyfruits.
