Personally, I think she held her ground. Blitzer was aggressive, but she said what she needed to say, spoke to her audience and ultimately came out a hero. I don't think most Democrats understand that Republican voters seriously believe that Obamacare is some sort of nuclear bomb on the economy and their "freedom". Sure, we can laugh and ridicule them, but they're not being disingenuous. The politicians are essentially actors in a horror film, but the voters are seriously frightened.
I think we're watching Citizens United unfold. And we should be frightened too.
