A majority of Americans who listened to President Trump's inaugural address gave the 16-minute speech a positive review, according to a new poll by Gallup.

Fifty-three percent of those who watched the inaugural ceremony last Friday, or followed news coverage of it, rated the president's address as "excellent" or "good." Only 20 percent said they were less than impressed.

Trump spent most of his speech focusing on the "America first" vision he built his campaigned around. But in a stunning departure from tradition, the new commander in chief also delivered a scathing indictment of the political establishment that stood in his way during the election.

"Their victories have not been your victories; their triumphs have not been your triumphs. And while they celebrated in our nation's capital, there was little to celebrate for struggling families all across our land," he said.

Despite earning a majority of the public's approval for his remarks, Trump's address was still seen less positively than the re-election speeches delivered by former Presidents Bush and Obama. Nearly two-thirds of Americans gave Obama's 2009 address a positive rating, and 62 percent afforded the same rating to Bush in 2005.

Similarly, a greater percentage of Americans described themselves as "more hopeful" about the next four years after Bush and Obama were sworn in for their first terms than did following Trump's inauguration on Friday.

Sixty-two percent of the public said Obama's speech in 2009 gave them greater hope for the country, compared to 39 percent who said the same after watching Trump speak at the Capitol.

The Gallup poll of 508 U.S. adults was conducted immediately after Trump's inauguration on Jan. 20. Results contain a margin of error plus or minus 5 percentage points.
