I don't agree that Obama was better than Washington. But this part of the article is also worth noting:
Forty-four percent of Republican voters polled said Washington was a better president than Trump, while 37 percent said Trump is better than Washington.
...The question was “inspired” by a recent Economist/YouGov Poll that asked voters whether Trump or Abraham Lincoln was a better “Republican president,” according to the poll. That poll found that 53 percent of Republicans said Trump was a better president than Lincoln, while 47 percent chose the Civil War-era leader.
