President Donald Trump sees a healthy US economy as his biggest success in the White House.
But Americans' glowing views of the economy have not yet translated to broad support for the president.
In a tweet Thursday morning, Trump highlighted Wednesday's Quinnipiac University poll that showed 66 per cent of voters view the economy as "excellent" or "good." That figure rose from 63 per cent in December, and is the highest reading since the university started asking the question in 2001.
The same poll, however, showed that economic optimism has not generated support for the job Trump is doing as president.
Only 36 per cent approve of Trump, while 59 per cent disapprove, the survey says. In December, 37 per cent approved of the job the president was doing, while 59 per cent disapproved.
Views on Trump's character traits "may serve to neutralize the optimism" about the US economy, said Tim Malloy, assistant director of the Quinnipiac University Poll.
Voters believe Trump is not honest by a 63 to 34 per cent margin, while they think by a 59 per cent to 39 per cent margin that he does not have good leadership skills, the poll says. In addition, respondents by a 59 per cent to 38 per cent margin believe he does not care about the average American.
"Those from-the-gut reactions from voters tell us that Americans are not yet connecting with the president despite a surging economy," Malloy told CNBC.
Another data point in the poll sheds some light on how Americans view the economy. A larger percentage of voters - 49 per cent - say they think Trump's predecessor President Barack Obama is more responsible for the current state of the economy, the poll shows. Forty per cent say Trump has more to do with it.
The White House did not immediately respond to a request to comment on the poll.
Trump, who won the White House partly on promises to kickstart American job growth and encourage companies to move foreign operations to the US, has repeatedly highlighted monthly jobs figures and stock market records as evidence that his agenda has worked.
The poll of 1,106 American voters, conducted from Jan. 5 to Jan. 9, has a margin of error of plus-or-minus 3.6 percentage points.
