Has Barack Obama been an advantage or disadvantage for the Democratic Party?

Right now he's a disadvantage for the party. He didn't keep most of his promising that got him elected. Get out of Iraqi and Afghanistan, he tried to stay in Iraqi and we're still in Afghanistan, to close gitmo. Then he pushed through the affordable care act, with the help of Nancy Pelosi, and her famous statement “But we have to pass the bill so that you can find out what is in it – away from the fog of the controversy.” the basically failed launch of the web site. Democratic's know this, you're not seeing Obama standing next to too many politicians, the left core of the party is mad, the republicans, have lots of talking points if they try to stand with Obama, so they distance themselves from him.
