Congress’ already dim job approval rating fell to a new record low of 9 percent this month, according to a Gallup poll.

The latest score is the lowest rating the polling firm has on record for the legislative body. It also represents a two-percentage-point decline from last month’s figure. The previous record low of 10 percent was recorded twice last year.

Researchers at Gallup said that last month’s government shutdown, the first in 17 years, did nothing to boost the public’s view of Congress. The effects, according to the polling firm, may linger.

“Americans’ views of Congress have not recovered, but instead have edged lower,” Gallup stated. “By contrast, Americans’ confidence in the economy has begun to improve in the last several weeks.”

Gallup data also shows that the frustration with Congress spans all political groups, as 9 percent of Republicans approve of Congress; 10 percent of Democrats; and 8 percent of independents.

Gallup conducted telephone interviews with 1,039 adults between Nov. 7 and 10. Its survey has a 4 percent margin of error.
