The first measurement of President Donald Trump’s job-approval rating shows Americans divided over his performance in his three days in the Oval Office.

Trump’s approval rating in the Gallup survey, conducted last Friday through Sunday, opens at 45 percent — the same percentage of Americans that said they disapprove of Trump’s first weekend on the job.

In fact, Trump is beginning his presidency with the lowest initial approval rating in the modern polling era, according to Gallup.

But while Trump’s first approval rating is improved from the poor reviews Americans gave to his presidential transition, it is also lower than previous presidents — a sign Trump has entered the White House without the same support from Americans that others have enjoyed. Barack Obama’s opening approval rating in January 2009 was 67 percent, George W. Bush’s was 57 percent in 2001, Bill Clinton’s was 58 percent in 1993, George H.W. Bush’s was 51 percent in 1989 and Ronald Reagan’s was also 51 percent in 1981.

Jimmy Carter’s first approval rating in 1977 was 66 percent, Richard Nixon’s was 59 percent in 1969, John Kennedy began his presidency in 1961 with a 72-percent approval rating and Dwight Eisenhower’s first approval rating in 1953 was 68 percent.

Trump’s initial approval rating is also lower than the scores for Gerald Ford (71 percent) and Lyndon Johnson (78 percent), who entered the Oval Office following – respectively – the resignation and assassination of their predecessors.

Trump’s initial approval rating also stands in contrast to Obama’s final score before his presidency ended last week: 59 percent of Americans surveyed from last Tuesday through Thursday said they approved of Obama’s job performance, though Obama’s average approval rating over his eight years averaged to just under 48 percent.

The Gallup presidential approval poll consists of a three-day rolling sample of interviews with approximately 500 American adults each day.

Among respondents contacted only on Friday evening, 39 percent said Trump’s inauguration made them feel “more hopeful” about the next four years, while 30 percent said it made them feel “less hopeful” and another 30 percent said it didn’t impact how they view the next four years. That is on par with reactions to the second inaugurals of Obama and George W. Bush, though far short of the 62 percent who said after Obama’s first inaugural they were more hopeful about the four years to come.
