Congress are at the bottom of the barrel with the country. As you saw in the title, only 1 out of 7 supports them according to the Gallup poll.
The poll was conducted about a week after the contentious fiscal cliff debate on Capitol Hill concluded and days after the new Congress was sworn in. That body has much ahead of it in the next few months - the U.S. will face default if the debt ceiling isn't raised, the across-the-board spending cuts known as the sequester will trigger on March 1 and the government runs out of funding later that month. Add to that some lawmakers' desire for action after the Newtown elementary school shooting and President Barack Obama's Cabinet nominees, and this Congress has a full plate.This is not the lowest rating of Congress. They hit 10% in August.
The 14% approval rating is about as well as Congress scored after the 2011 debt ceiling showdown. In August and September of that year, they scored 13% and 15% approval ratings. The stalemate on Capitol Hill led to the creation of the sequester and to the downgrade of the U.S. credit rating.
