Americans rate only car salespeople below Congress in terms of honesty and ethics.

Just one in 10 Americans rate the honesty and ethical standards of lawmakers as high or very high, according to a Gallup poll released Monday. People ranked nurses at the top of the 22 professions polled, with more than eight in 10 rating them as highly honest and ethical. Rounding out the top five are pharmacists, medical doctors, engineers and dentists. Car salespeople rank lowest, joining members of Congress, advertising practitioners, stockbrokers and HMO managers in the bottom five. Journalists fell in the middle, just below bankers and right above business executives.

While people have never perceived Congress as very honest or ethical, the abysmal numbers in this latest poll are especially low. That may be due in part to the looming "fiscal cliff," which could strike a blow to the fragile economy and send taxes up if Congress fails to act before the January 1 deadline.
