It's all Kabuki theater to cover up the truth that President Obama made a backroom deal with the for-profit hospital industry that the final health care bill would not include a national public option.
Popular action is the very definition of democracy. It doesn't happen without us, and it isn't a human right upheld by some magic fairness-fairy. If the public option's not in the bill, it's because we haven't shown up to demand it.
If you break your pledge and vote for a health reform bill without this minimally robust version of the public option, you've ensured that even with a Democratic majority, all "reform" will be limited by your Blue Dog colleagues.
From the moment he was elected, Obama has governed not as a progressive liberal but as a corporatist liberal. Progressive liberals hoped Obama would be like FDR. Instead, he's been like Bill Clinton on steroids.
