The kids on Obama Block want an exclusive club: they want to make their own rules (and enforce only those that make Obama look good); they want to kick anybody out who doesn't obey "their" rules; they want everybody to behave according to their rules; and they can behave any way they want to because it is their rules.
Obama isn't ready for this job. His followers are concerned about this; otherwise they would use debate and dialogue to counter those of us who see him a losing candidate in November (something many of us have said for months now).
Obama's Rules include dirty tricks and "stealth" dirty tricks. But, again, because the kids on Obama Block make their own rules and enforce only those that they think make Obama (and themselves) look good, these tricks are ignored.
Obama is not ready for this job. He has proved this in myriad ways, his comments in SF being just the latest example.
