Many U.S. citizens doubted Donald Trump's ability to lead the nation in critical areas expected of the presidency, a Gallup poll published Monday showed. The results came as Pew Research Center shared separate findings indicating great uncertainties regarding the new administration.

Gallup found that less half of respondents believed Trump would successfully "handle an international crisis" (46 percent), "use military force wisely" (47 percent) or "prevent major scandals in his administration" (44 percent). The President-elect performed poorer than his predecessor President Barack Obama, Democratic presidential rival Hillary Clinton and last Republican President George W. Bush in every comparable category. 

Trump's confidence rating was highest in his ability to "work effectively with Congress to get things done" in which he scored 60 percent approval. Trump painted himself as a Washington outsider and has proposed sweeping reforms in legislature regarding taxes, jobs and immigration. Respondents still had higher hopes, however, for past presidents Obama (89 percent) and Bush (74 percent). Clinton's rating was not available in this category.

Gallup's survey was released weeks after a number of Pew Research Center analyses that concerned the nation's views on Obama's legacy and Trump's incoming administration. One poll showed that only a tenth of Republicans felt Obama had made any progress in solving the country's major issues. Another found that black respondents were most likely to think race relations would worsen under Trump.

Trump, who is set to be sworn-in to office Jan. 20, has vowed to "Make America Great Again." He has also pledged to reverse high-profile diplomatic positions taken by Obama in the final days of his presidency, including the condemnation of Israel for its settlement building on Palestinian land, illegal under U.N. law, and sanctions against Russia, which Obama's administration joined the FBI and CIA in accusing of interfering in the presidential elections on Trump's behalf.

Gallup's poll was conducted Dec. 7-11, 2016, surveyed 1,028 adults and has a margin of error of 4 percentage points.
