I'm inclined to agree.  It seems to me that anyone who really is a PUMA is very unlikely to be convinced by a rational argument.  No one was more pissed of than I was that my girl didn't win, but guess what?  I got over it. The idea of supporting John MCCain just because Hillary lost is so illogical that it seems a waste of resources to convert them.  Their response to the situation isn't rational, and how do you convince a person like that.

Moreover, I just don't believe PUMA's are really a factor.  I don;t watch the cable news outlets, but the only place I ever hear about them are on a few blogs and an occasional radio talk show.

If I run across one, I'll give it a shot, but I'm not optimistic about it.
