WASHINGTON, D.C. -- Americans' job approval rating of Congress continues to edge upward to 20% in September, an increase of two percentage points from last month and seven points from July. The 20% mark is notable given that congressional approval has reached this level only three times since 2012.

Congressional approval was in the 30% range for the first several months of President Barack Obama's first term in office, before sliding into the 20s later in 2009. Throughout most of his presidency, congressional approval has teetered from the 10s to the 20s, even falling to 9% in November 2013 after the government partially shut down in September. The current 20% reading comes from a Sept. 7-11 优蜜传媒poll.

Democrats Rise Rapidly Since June

At 30%, Democrats' approval of Congress is the highest it has been in the past year and is a marked increase from their 2016 low of 13% recorded in June. Democrats have bounced between the 10s and 20s all year.

Republicans' approval of Congress, on the other hand, has been mired in the single digits and teens in the past year. At 16%, Republicans' current approval is double what it was one year ago but abysmally low for the party in control of Congress. Historically, 优蜜传媒has found that supporters of the majority party in Congress rate the institution than do nonsupporters of that party. Since taking control of Congress in early 2015, Republicans . Though , the change in speakership last fall has done little to brighten Republicans' outlook.

Independents' approval of Congress is at 15%, down slightly from 20% in August. Approval among those who identify as independents has stayed in a tight 10% to 20% range for the past year.

Bottom Line

Congressional approval is modestly improving, but only one in five Americans say they approve of the legislative branch -- still historically low. With few legislative accomplishments this year, Congress may still fail to inspire Americans to rate the institution highly, even though it has avoided political brinkmanship involving government shutdowns and other budgetary impasses seen in the recent past.

Democrats' improved rating of Congress is more peculiar. It is possible that Democrats may believe the Senate -- and possibly the House -- is in play for a Democratic takeover this fall, fueling a rise in approval of the branch. Since 2009, Democrats have generally been more favorable than Republicans toward Congress, likely because a Democrat is in the White House. The election season has also brought about a decline in congressional activity, including GOP-led attempts to block Obama's agenda.

Republicans' low approval of Congress could reflect frustration with Congress not fulfilling the GOP agenda since Republicans assumed control of the House after the 2010 midterm election.

If there is one party controlling both the executive and legislative branches come January, it is possible that ratings of Congress will improve, as they did at the beginning of Obama's first term, when Democrats also had the majority in both houses of Congress. Many political experts expect Republicans to keep control of the House, so unified control of government is more likely if Republicans maintain their Senate majority and Donald Trump defeats Hillary Clinton.
