Bachmann signed his pledge....the others, apparantly, did not. I really don't have an issue if this guy is attempting to sway voters. Without digging extensively into his pledge he asked candidates to sign, it seems to be very conservative in nature. Matter of fact, if you read the reasons Romney and a few others didn't, it reinforces thier rino status.
But I don't know much about the guy, just feels, on the surface, much ado about nothing.
