In 2007, John McCain criticized Democratic contenders for offering what he called costly universal health care proposals that require too much government regulation. While he said he had not studied Democratic candidate Hillary Clinton's health-care plan, he said it was "eerily reminiscent" of the failed plan she offered as first lady in the early 1990s.
I think they put some lipstick on a pig, but it's still a pig," he said of her proposal.
He's not even the first, other politicians have also used the phrase in recent years, including Vice President Dick Cheney, Sen. Maria Cantwell of Washington state, Sen. James Inhofe of Oklahoma, Sen. Mitch McConnell of Kentucky, Rep. John Mica of Florida and Rep. Tom Tancredo of Colorado, among others.
Torie Clarke, a former McCain adviser, even wrote a book called, "Lipstick on a Pig: Winning In the No-Spin Era by Someone Who Knows the Game."
And so - I'm unsure why McCain's camp is demanding an apology from Senator Obama.
Unless, of course, he gave one to Hillary back in 2007.
