Researchers surveyed Arizona State University students around the time of President Donald Trump’s inauguration in 2017, and some had stress scores on par with that of school shooting witnesses’ seven-month follow-ups.

Twenty-five percent of the 769 students, who were an even mix of genders and races and socioeconomic backgrounds, reported ‘clinically significant’ levels of stress.

The most severe cases were seen among women, black, and non-white Hispanic students, who were 45 percent more likely to feel distressed by the 2016 run between Trump and Hillary Clinton.
