I tend to agree with Ezra Klein about not taking Lieberman seriously on this filibuster.
Make no mistake, the man is arguably the most insufferable and intolerable senator -- ever. But he's basically doing what he always does. Making everything about Joe in order to get something else. This isn't about the public option or healthcare reform. This is Lieberman pissing on liberals while throwing around his swing "independent" status.
Nevertheless, help us Connecticut. In 2012, please, please help us. Don't forget that Lieberman, whether serious or not, tried to filibuster healthcare reform. This is unforgivable -- even beyond the McCain campaigning.
