Despite all the controversy attached to his presidency, Donald Trump has managed to retain a relatively consistent approval rating in the last two years — especially when compared to predecessors in the modern era.

The president's approval rating has climbed some in recent weeks after a significant decline in January, reverting to around the average during the last two years.

Perhaps it's the tribalism in American politics or the fragmented news ecosystem or the president's skills as a communicator — but, for some reason, Trump hasn't experienced the wide fluctuations of his predecessors.

He also, of course, remains historically unpopular.

According to Gallup, the president's rating changes have stayed within a 14 percentage point range.

Other presidents — even those who only served one term — have experienced wider swings in their popularity over time. The late George H.W. Bush, for example, saw his popularity drop from 89% in February 1991 to 29% the following summer, a massive change.

Here are all the presidents, and their popularity ranges, since Harry Truman:
