Left Wing Nervous about Obama’s Administration

I thought it was crazy when the McCain campaign went so far as to call Obama a "socialist," so I really thought this article on NPR was a little comic. The new concern seems to be that the Obama administration will be without any truly liberal components. Sure, this may be better in the eyes of the majority of American, but will he lose his liberal supporters before he even gets started?
