I think the pig soundbite maybe a little overblown, BUT I believe he meant it. The lipstick on a pig sounds like a line a cityslicker would write for a sitcom set in either the South or out here. It isn't an idiom that a cityslicker that has NO connection with hicks would use, and with his history this campaign of showing his disdain for us hicks and his first attack against Sarah slamming the fact she was a mayor of a small town. I'm forced to come to the conclusion HE MEANT IT! even if he didn't think it through. Sort of the whole out of the overflow of the heart the mouth speaks that Apostle Paul wrote about.
