Eighty-nine percent approved of Trump when he took the Oath of Office a year ago, and Republican approval did not dip below 77 percent since then, according to Gallup's tracking numbers.
"This year marks a significant change in our trends", wrote Gallup's managing partner, Jon Clifton.
The US did score big in another area, though, with America's disapproval rating reaching new heights of 43 percent, falling far behind Germany (25 percent), China (30 percent) and Russian Federation (36 percent).
"We were kind of thinking we were going to relax and put Trump behind us and just watch all the great promises that he gave us, and watch him make America great again", said Michigan Trump supporter Meshawn Maddock.

"We will be there to replace" the USA on funding of climate science, Macron said during a major climate meeting where Trump was not invited.
"This president hasn't even been in office for a year, and look at all the things he has been able to get done, by sheer will in many ways", said Utah Republican Senator Orrin Hatch, who also announced recently he would not run for re-election this year.
"While advancing American influence - one of the four pillars of the administration's new national security strategy - may begin with building up wealth and power at home, as Trump has stated, it can't be achieved without a strong commitment to and close cooperation with partners and allies overseas", the report says.
"While China has consistently attempted to expand its global reach, it still has no soft power - worldwide, there is no Chinese version of blue jeans, cinema, TV shows, way of life, music, and the like. President Xi's "Chinese Dream" is a transparent attempt to mimic the American model".
