re: "Amazing how no one on the left side rails into Obama or Biden?"
For myself, I really like Obama for president. And I really like Biden for president (Yes, I know he is running for VP. But I strongly believe that the way to evaluate a VP candidate - for your own voting preference - is to decide if he is a good match for the presidency).
That's why I don't have a lot of bad to say about them. I'm sorry you guys don't like your candidates better.
