Washington (CNN) Donald Trump will become president Friday with an approval rating of just 40%, according to a new CNN/ORC Poll, the lowest of any recent president and 44 points below that of President Barack Obama, the 44th president.

Following a tumultuous transition period, approval ratings for Trump's handling of the transition are more than 20 points below those for any of his three most recent predecessors. Obama took the oath in 2009 with an 84% approval rating, 67% approved of Clinton's transition as of late December 1992 and 61% approved of George W. Bush's transition just before he took office in January 2001.

Trump's wobbly handling of the presidential transition has left most Americans with growing doubts that the President-elect will be able to handle the job. About 53% say Trump's statements and actions since Election Day have made them less confident in his ability to handle the presidency, and the public is split evenly on whether Trump will be a good or poor president (48% on each side).

The President-elect dismissed the poll findings on Twitter: "The same people who did the phony election polls, and were so wrong, are now doing approval rating polls. They are rigged just like before."

Rep. Sean Duffy, a Trump supporter, said the President-elect's ongoing battle with the media has hurt his image.

"What's happening here is the public fight that Mr. Trump is having with CNN and other media groups has taken some skin off his poll numbers and it's gone down," he told CNN's Chris Cuomo Tuesday on "New Day."

Across all three of these measures, Americans' impressions of Trump have worsened since November. In that time, disapproval of his handling of the transition has climbed seven points to 52%, the percentage who think he'll do a good job has dropped five points, and the share saying they have lost confidence in Trump's ability to be president grew 10 points.

Trump's favorability rating, a measure often seen as a read on a public figure's personality rather than the job he or she is doing, has taken less of a hit, decreasing by just 3 points to 44%. That change falls within the poll's margin of sampling error and is not statistically significant.

Despite these declines, many Americans remain confident that Trump will achieve several signature campaign promises, with most saying it's at least somewhat likely that he will impose tariffs on companies that manufacture goods in Mexico (71%), renegotiate NAFTA (61%) and create good-paying jobs in economically challenged areas (61%).
