Absolutely possible. I'm human too.

I see two general types of Dean supporters in threads around the blogosphere. (I stopped reading the Dean blog itself because I OD'd on exclamation points.) There's the "Dean's great! I support Dean! End of argument!" types, whose arrogance do the candidate and his more thoughtful supporters no good and actually alienates folks.  (In fairness, Wes Clark seems to attract a fair number of these types also).

Then there are the more rational supporters who attempt to analylize and then offer honest opinions.  Folkbum comes immediately to mind, but there are many others.  This group, of which I'd like to think I'm part, has it's biases, too.  We've picked a candidate to support, after all, and we are interested in persuading others to support him.

I may be guilty of being myopic and focussing on the latter group while ignoring the former when I make remarks like the one you highlight. I tend to do this with Clark supporters, too, bypassing the starstruck in an attempt to try and understand what the man's appeal is and why it is so lost on me.
