Martin: 'You can keep it' - a new breed of presidential fibbing

No, I'm not going to use this column to throw darts at President Obama's, "If you like your health plan, you can keep it," lie. That dead horse has been flogged enough for now. Instead, I am going to characterize the type of fib he made to the American public and how it is a whole new breed of presidential dishonesty.

It is no revelation that presidents lie. Find me one who hasn't lied while in office, and I'll trade you a unicorn for that name.

For centuries, these guys have been some of the greatest liars of all time. And whether the untruths they've told have been whoppers or little whites, their lies usually share a common purpose -- to get that president what he wants, typically advancing a divisive agenda.
