Obama is slick - He did call Palin a pig and refer to McCain an old fish

They call it plausibly deny ability.  The speech Obama gave was written and rehearsed.  He talked about change and calling it one thing (change didn't make it change).  This gave him the cover he needed to call Palin a PIG.  Just like he flipped Hilary off.  He is a Chicago thug politician.  Bill Clinton can see one, it takes one to know one.
