Not surprising, really, when the Perry’s campaign strategy of ‘tear down the other guy to make me look better’ cascades down to his cronies. Modus operandi from the beginning.
Perry never attacked ANYONE until they (Romney) attacked him first. The first debate Perry appeared in, Romney cut him at the knees. You apparently choose not to remember that. The only “other” attacks from Perry have been second-hand allegations from the Cain camp and promptly withdrawn.
