So why are they reelected?

Rasmussen Reports:

Approval of Congress' job performance is down to single digits again for the first time since early September.

The latest Rasmussen Reports national telephone survey of likely voters found that only nine percent (9%) give Congress good or excellent ratings, while 54% give the legislature poor marks. Just one-out-of-50 voters (2%) think Congress is doing an excellent job.

The last time the ratings were this low was on September 9. In late November, 12% gave Congress good or excellent ratings. This is now the fifth time congressional ratings have fallen below 10% since June 1.

Since the election when Democrats grew their majorities in both the House and Senate, Congress has been in the news struggling unsuccessfully to pass an unpopular bailout plan for the Big Three automakers.

Even only 14% of Democratic voters rate the performance of the Congress led by their own party as good or excellent, compared to five percent (5%) of Republicans and six percent (6%) of unaffiliated voters. Thirty-five percent (35%) of Democrats say the legislators are doing a poor job, and 69% of Republicans and 63% of unaffiliateds agree.

Can the Democrats sustain their majority with this kind of approval rating? Logic says they should not, but experience suggest they will continue to get away with their poor performance.
