It's probably too late to do anything about it.
Here's a partial list of the guilty parties who caused the Democratic party to fail.
1- Barack Obama: His weak leadership, his attempts to please everyone, to be like Lincoln and his lies and betrayals, selling out the public option, fighting against auditing the FED, allowing abuses of the constitution Bush initiated-- these added up to major reason the Dems will lose in November. Obama had a chance to strengthen reform. Instead, he sabotaged and weakened it. He appointed DLC right wing leaning people to his administration, Banksters who were part of the problem to financial posts and was weak and passive with the military, letting them tell him what to do, failing to take the responsibility as Commander in Chief to make the tough choices.
3-Rahm Emanuel: he played a major role, as head of the DCCC, recruiting bluedog dems to fund and run against strong, viable progressive Democratic primary candidates. That pack of worthless bluedogs in the house-- blame Rahm Emanuel for a lot of them, and for their strength. And then, as Obama's chief of staff, he's been there to root for the right wing angle, the corporate angle, to cut deals with corporations that stabbed constituents who trusted Obama in the back. He worked for Obama then, but he could have advised him to be a better president instead of one who, so far, will go down in history as a failure.
4-Nancy Pelosi" Her impeachment is off the table policy, starting in 2006, when the Dems took the house, prevented investigations into the illegal and corrupt Bush Cheney White House. This will go down in history as a massive tactical error and moral failure.
There's no doubt in my mind that the biggest cause was Barack Obama. His weak support and passive engagement in the legislative process was bad, very bad for the Democrats. His abject failure to be a strong, decisive leader in the face of the Gulf BP oil disaster pretty much insured that he would go down in history as a one term president. That doesn't have to be the case. He could redeem himself in many ways. But so far, holding hope that Obama would do the right thing when it counts has been a futile effort. Yes, he's made a few things happen. But for the most part, the legislation he's been involved in getting through has been weak and afflicted with loopholes and give-aways for big corporations. On the other hand, he's been far worse than Bush on some issues, like whistleblowers.
Unless a miracle happens and the Democrats morph into something very different, unless Obama wakes up from he nightmare he's caused all we progressives to be living in, the Democrats will probably lose the house and by 2012, perhaps the senate and probably the White House, because they will be too inflexible and blind to realize that Obama doesn't have a chance.
There are more to blame. I invite you commenters to add to the list.
Meanwhile, we had best be bracing for a few years, maybe six or more, of right wing hell... again... and facing the reality that the USA is really the CSA-- the Corporate States of America.
