Barack Obama demonstrates that he is a master of the increasingly popular liberal retort of "false equivalence" wherein there is only one legitimate position (the liberal one) and all other arguments and/or comparison between policies by opponents are not.
"I think that there is oftentimes the impulse to suggest that if the two parties are disagreeing then they're equally at fault and the truth lies somewhere in the middle. And an equivalence is presented which I think reinforces peoples' cynicism about Washington in general. This is not one of those situations where there's an equivalency."
In other words, the media should ignore his critics because they don't hold legitimate views.
There is such thing as "false equivalence" but it is most commonly deployed by liberals who don't have any other arguments in a debate. Ask them to explain why and how something is a false equivalency and they usually pack their bags and don't respond or pull out the old standby "if I have to explain it to you, then you are worthy of the conversation".
