Now you may think that this disapproval comes mainly from one or two political sectors of the country -- that one party may be so negative it is bringing the average approval percentage down. That would not be true though (as the chart above shows). The chart is from a new Gallup Poll (taken between March 7th and 10th of a national random sample of 1,022 adults -- with a margin of error of 4 points).
The truth is that Republicans, Independents, and Democrats all have an equally bad opinion of Congress. Before the 2010 election Democrats had a slightly better opinion of Congress than the other two groups did, but that election, which put the GOP in control of the House, caused Democratic approval to drop from 38% to below 20%. Currently all three political groups have a very low opinion of Congress. Here are the approval numbers:
Republicans...............15%
Democrats...............13%
Independents...............11%
If there's any saving grace for Congress, it's that their numbers didn't fall much after they failed to find a compromise to stop the sequester. But they may be because their numbers are already so low they really couldn't fall much lower.
