I used to work with one like that. He'd trot out the Obamessiah platitudes, and when I called him a liberal or lefty, he'd say (with all seriousness), "I'm an independent." I'd say, "No, you're an Obot."
One that comes to mind hates the right, hates the tea party, hates conservative media, gets all his news from MSNBC and other MSM outlets, continually blasts Rush, Agrees with everything the left does, and voted for Obama last time and is cheerleading for Obama this time. But yet, insists that he is not a liberal. He insists that he is an independent.
