Barack Obama was David Letterman's special guest on Wednesday's "Late Show," and during the appearance, Obama vigorously denied that his "lipstick on a pig" comment was directed at Sarah Palin, calling the notion silly and Palin herself "a skilled politician."
"This is a sort of silly season in politics, not that there's a non-silly season, but it gets sillier," Obama said, continuing: "And it's a common expression in at least Illinois. I don't know about New York City. I don't know what you put lipstick on here."
The Democratic presidential nominee said he used the expression as a metaphorical way of contending that Republican rival John McCain's proposed economic policies won't change things in Washington, D.C.
"Just calling [ideas] change, calling them different doesn't make it better, hence lipstick on a pig," Obama explained.
And he added: "Keep in mind, technically, had I meant it this way, she [Palin] would be the lipstick … The failed policies of John McCain would be the pig … just following the logic of this illogical situation."
Earlier in the day Obama accused McCain's campaign of resorting to "lies and phony outrage" regarding outcry over the "pig" comment.
