The failed effort to repeal and replace Obamacare is taking its toll on President Donald Trump's already low poll numbers.

The latest Gallup poll - which shows a three-day rolling average of daily figures - shows President Trump's approval rating is 40 percent, a drop of 1 percentage point from the previous results. Fifty-four percent of those polled said they disapprove of the job the president is doing.

Gallup's poll comes just after Trump's failed efforts to move the American Healthcare Act through Congress. The bill was withdrawn from consideration on Friday in a move widely seen as a failure for Trump and Speaker of the House Paul Ryan, who supported the bill, and a victory for former President Obama's signature healthcare legislation.

The president commented via Twitter on the bill's failure.

"ObamaCare will explode and we will all get together and piece together a great healthcare plan for the people. Do not worry!" the president wrote.

Trump's numbers in Gallup polls have been hovering around the 40 percent mark since his inauguration in late January, historically low approval ratings as compared to other presidents during the initial months of their first terms. At the same point in his first term, former President Obama's approval rating hovered around 60 percent; former President George W. Bush's was in the high 50s.

Gallup's poll includes results from 1,500 adults with a margin of error of plus or minus 3 percentage points.

The Gallup numbers are similar to those from the Rasmussen Reports, a Republican-leaning survey. Rasmussen's Monday tracking poll has Trump's approval rating at 45 percent and his disapproval rating at 54 percent.

The latest figures include 28 percent of likely voters who said they strongly approve of the way Trump is performing as compared to 44 percent who strongly disapprove. At the beginning of March, 34 percent strongly approved of the job the president was doing compared to 40 percent who strongly disapproved.

Last week, ahead of the failed healthcare vote, 35 percent of those included in the Rasmussen survey strongly approved of the job the president was doing; 42 percent strongly disapproved.

The Rasmussen poll includes results from 1,500 likely voters with a margin of error of plus or minus 2.5 percentage points.
