Obama said it about McCain's policies yesterday
McCain's supporters have morphed that into an insult against Sara Palin, as she is "the only one of the four candidates who wears lipstick."
McCain has himself used the expression several times in the campaign, always to point out just what Obama was trying to point out, which is that you can make a small change in the packaging of something but it's still the same inside.
Obama is right that this tempest in a TV screen is EXACTLY WHAT MAKES ME HATE POLITICS AND DESPAIR FOR OUR NATION. WE'RE AT WAR, FOR GOD'S SAKE. WE'RE BANKRUPTING OURSELVES. OUR KIDS ARE GETTING an inferior education and everybody's getting inferior health care. Our population is skyrocketing. The Globe is warming up.
And on the other hand, it's a distressingly sexist-sounding statement. There's too much in the culture that links women, lipsticks and pigs. Like the world "nigardly", which doesn't mean what it sounds like it means but is close enough that no smart person uses the word any more, let's retire this folksy statement. In the end, it does only harm.
