Guest from Sanity,
If you bothered to read or listen to what Obama actually said in that "lipstick" speech, you'd see that it was neither John McCain nor Sara Palin that he was calling a "pig," it was the policies of the Bush/Cheney administration, which McCain wants to continue.

Sadly, I cannot find the video of Obama's actual speech on line any more, but here is what he said in the "lipstick" portion:
([Here's John McCain's message to Washington] "... Watch out George Bush! Except for economic polici, health care policy, tax policy, education policy, foreign policy and Karl Rove style policy, we're realy gonna shake things up in Washington.   
That's not change!
That's keeping the same thing and calling it something different. You can't ... You can put lipstick on a pig ... (crowd roars and applauds) and it's still a pig. You can't wrap an old fish in newspaper and expect not to smell as bad after 8 years. ... "

If you think Barack was alluding to Palin as the "pig," you've either been grossly misled by YouTubes and blogs and ads that have taken the "pig" comment out of context and deliberately, inaccurately attached it to a picture of Palin or to her convention speech -- or you're deliberately choosing to distort the plain facts that are right in front of your nose.

I'll give you the benefit of the doubt and assume that you, like a lot of the public, have heard only the spin and distortions and not the actual facts.

Peace
