I'm going to don my tinfoil hat for a moment.
What if this fustercluck of a congress is intentional? By going so far left, they knew there would be a revolt from the center and right, which would cause many bluedog dems to lose this year. Then we are left with only a slight dem majority, maybe. Either way, little or nothing gets done during the rest of Lord Zero's first term.
That gives the dems and Lord Zero a campaign strategy for 2012, to get an even greater super majority and Lord Zero's 2nd term. Okay, maybe that is giving them too much credit.
