Is It Wishful Thinking or Lying?

(By Tom Bevan, Real Clear Politics) - Here's a question: if I went out and made a claim I believed but no one else thought possible - that a greyhound could outrun a cheetah, for example - would that be considered a lie or just naive, wishful thinking?

The reason I bring this up is because Bob Herbert made a rather astonishing admission about President Obama's health care plan in his column on Saturday:

The president also said, as he estimated the cost of his proposal at $900 billion over 10 years, that he “will not sign a plan that adds one dime to our deficits — either now or in the future.”

I'm sure he means it. But I have not spoken to anyone, either on Capitol Hill or elsewhere, who believes that is doable. (emphasis added)
