I'm a soccer mom, and I am an educated voter. You don't win votes by demeaning the audience you are trying to sway. Not all "soccer moms" or "hockey moms" are idiot Nat'l Enquirer readers.
There is so much corruption in Palin's past, so much vapid ignorance. Point that stuff out. Don't use Hockey Mom as a derisive term. You're going to turn off way more people than you will win with taunts like that.
