The chart above reflects the results of the latest Economist / YouGov Poll -- done between January 28th and 30th of a random national sample of 1,500 adults (including 1,264 registered voters), with a margin of error of 3 points (2.9 points for registered voters).
The poll's respondents were asked if, compared to the past, is the United States more or less respected by other countries today. The result was overwhelmingly negative. About 55% of adults (and 58% of registered voters) said the U.S. was less respected now. And that's the opinion of nearly every demographic group. The outlier was the Republican group (where a plurality of 45% said the U.S. is now more respected).
Republicans just don't want to admit that their favorite demagogue has done a terrible job in dealing with other countries (both friends and enemies). Everyone else knows better. They know Trump has seriously damaged the reputation and standing of the United States in the eyes of the world.
