President Trump is back in Washington, D.C. this week after his first overseas trip – but his approval ratings are stuck right where he left them.

The number of voters who disapprove of the president's job performance continues to exceed the number of voters who approve – and the popularity of Mr. Trump's biggest domestic policy initiative, the repeal and replacement of Obamacare, also remains lackluster.

Forty-five percent of voters in a Politico/Morning Consult poll released Wednesday said they approve of Mr. Trump's performance on the job, while 50 percent disapprove.

Voters in that survey were even more sour on the GOP health care proposal, dubbed the American Health Care Act. Thirty-eight percent said they approve of the AHCA, while 47 percent said they disapprove.

(One interesting, unrelated finding: support for Mr. Trump's impeachment reached a new high in the Politico survey. Last week, 38 percent of respondents voiced support for impeachment; this week, that number reached 43 percent. Forty-five percent, though, said they don't want Congress to impeach the president.)

In an Economist/YouGov survey released Wednesday, only 40 percent of voters said they approve of the job Mr. Trump is doing as president, while 53 percent said they disapprove.

And in that survey, the AHCA again received poor marks: 28 percent said they approve of the GOP's health care plan, while 48 percent said they disapprove. Twenty-four percent said they have no opinion.

In a Reuters poll released Tuesday, 40 percent of voters said they disapprove of the president's job performance, while 55 percent disagreed. And in a Gallup poll also released Tuesday, Mr. Trump's approval rating stood at 41 percent, while his disapproval rating stood at 53 percent.

The Gallup poll surveyed 1,500 Americans between May 28 and 30, and it has a margin of error of plus or minus three percent. The Economist poll surveyed 1,269 registered voters from May 27 through 30, and it has a margin of error of plus or minus 3.2 percent. The Politico poll surveyed 1,991 registered voters nationwide, and it has a margin of error of plus or minus 2.2 percent. And the Reuters poll surveyed 2,073 Americans over a five-day period ending on May 29.
