More Americans were optimistic during the early months of Barack Obama's presidency that he was bringing change than are optimistic today about Donald Trump.

Fifty-four percent of Americans say Trump has not made progress on his goal of changing the way Washington works--he campaigned on a pledge to "drain the swamp"--and only 40 percent say he has made such progress, according to the latest Gallup poll.

In April 2009, a similar point in Obama's Democratic presidency, 53 percent said Obama had made progress in changing Washington while 45 percent disagreed.

Gallup found that 78 percent of Republicans say fellow Republican Trump has made progress but 79 percent of Democrats and 59 percent of independents say he hasn't made progress in changing the capital.

At the 100-day mark, only 41 percent of Americans said Trump was doing a good job, according to Gallup. In contrast, Obama's job approval rating was 63 percent.
