There is a lot of competition for that title, but a top contender would have to be this comment during the third 2008 debate with John McCain (see below link).
It was moderated by Bob Schieffer of CBS who said next year there would be and “astounding $455 billion deficit,” and Obama’s proposals would add another $200 billion to the deficit. The then Senator responded “What I have done throughout this campaign is to promise a net spendng cut.”
He described himself as a “strong proponent of pay as you go (PAY-GO). Every dollar that I have proposed spending, I have proposed an additional cut. So that it matches. . . We need to eliminate a whole host of programs that don’t work. I want to go through the federal budget line by line.”
Unfortunately, all of this was a complete lie. Obama never considered a net spending cut and of course it was not included in his proposed budgets. PAY-GO was passed by the Democratic Congress in early 2007, but they never once complied with it. The real farce was the news media which portrayed liberal Democrats as deficit hawks in 2006 and 2008.
Some of the other contending statements for biggest lie would be:
- I’ve done more for Israel’s security than any President ever.
- The GOP is responsible for Obama jobs bill not passing.
- Then you’ve got their (GOP) position which is dirtier air, dirtier water and less people with health insurance.
- The rich don’t pay their fair share.
- The health care bill will not increase the deficit by one dime.
- If you like the health care plan you have, you can keep it.
- We have run out of places in the US to drill for oil.
- We will cut deficit in half by end of the first term.
- Health care negotiations will be covered on C-Span.
- The unemployment rate will be 5.3% with the stimulus.
- “I am not somebody who promotes same-sex marriage”.
- Guantanamo Bay will be closed within a year.
- Didn’t know Jeremiah Wright was a radical.
- We will have the most transparent administration in history.
- I have visited all 57 states.
