Oh, no doubt. But then I guess some could still blame the Democrats because they didn't change the Senate rules (the nuclear option as Repugs called it a few years ago.)
If you want to, you can find some way, no matter how convoluted, to blame the Democrats for everything. Just watch Fox "News" for 5 minutes to see how it's done. If you've got a few spare IQ points you're bound to lose... But the facts are out there for those who really want the truth. And as my momma says, the proof is in the pudding. 8 years of Republican rule and obstruction gets you to where we find ourselves today. Hopefully, at a minimum, the country has learned enough about their mistakes to put a solid Democratic majority back in place in both houses of Congress. That level of control, even with a Republican President, has worked for decades. Republican and Democratic Presidents together "won the cold war" with a Congress controlled by Democrats for most of 5 decades.
But because of the clusterfuck we find ourselves in now, we need to go a step further. We can't just have someone at the top vetoing all of the ideas flowing up from Congress. We need someone serious about tackling the problems George W. Bush has created. Someone who is fired up and ready to lead! Someone with youth on his side. Someone who can build an administration that won't be filled with incompetent cronies left over from the last 8 years. That man is Barack Obama.
