WASHINGTON, D.C. -- One in five U.S. adults (20%) in May approve of the job that Congress is doing, remaining unchanged from last month. Nearly three in four (74%) disapprove.

These data come from Gallup's survey of 1,011 U.S. adults conducted from May 3-7. On May 4, during the course of the polling, the U.S. House of Representatives voted to repeal the Affordable Care Act. The survey also occurred within a week of Congress' adoption of a spending package to avert a potential government shutdown.

In the midst of these events, Congress' current approval rating is down from 28% in February. The , measured shortly after President Donald Trump's inauguration, was the highest approval rating for Congress among Americans since 2009 and was up from 19% in January. Approval of Congress remained elevated, at 24%, in March but fell to 20% -- nearly the pre-inauguration level -- in April, where it remains.

However, unlike this year when Congress' post-inauguration bump lasted only two months, in 2009, the increase lasted eight months. Congressional job approval remained higher than 30% through September 2009, then dropped to roughly a pre-inauguration level of 21%.

Republicans' Approval Down by Nearly Half Since February

Twenty-eight percent of Republicans say they approve of the job Congress has been doing, similar to the 31% who approved in April. However, this is down 22 percentage points from 50% in February, the highest approval rating for Congress among Republicans since November 2006 (50%).

The reasons for this collapse in approval among Republicans may include frustration with Congress' inability to pass much of the legislation that Trump and the GOP favor. The U.S. House of Representatives was initially unable to repeal the Affordable Care Act, and Trump's plans for tax reform, as well as increasing spending on infrastructure, remain stalled.

The poll dates span the House's successful vote to repeal the ACA, meaning it is unclear what effect, if any, that legislative achievement may have had on Republicans' views of Congress.

Among Democrats, approval of Congress has been steady at 10% in April and May. Democrats' approval of Congress has only fluctuated slightly since Trump's inauguration, hovering between 10% and 12% since February.

Bottom Line

Republicans had high hopes for the passage of policies they supported after the GOP captured the presidency and Congress in the November elections. Those hopes translated into a spike in approval for Congress among members of the party after Trump's inauguration in January. However, the realities of the difficulties of governing, even when a single party is in control of the legislative and executive branches, appear to have negatively affected Republicans' approval of Congress. The recent House vote to repeal the ACA may yet result in an increase in approval for Congress among Republicans, but no immediate effect was evident in the May survey.

The initial spike in approval among Republicans had driven overall support for Congress up in recent months. However, with Republican optimism waning, Congressional approval among the public as a whole has dwindled back down to the pre-inauguration level.
