Lipstick, pigs, & female dogs

And just a quick note about the lipstick thing: If it is supposed that Obama's comparison of McCain's economic policies to a pig with lipstick was somehow really about Palin, shouldn't somebody be bringing up Palin's insult to hockey moms, when she essentially called them pit bulls with lipstick? And you know what they call a female dog, after all.... Is this really the line of reasoning (if I may take liberties with the term) that they want to follow?
