Brauer explains that, from 2012 to 2016, Democratic candidates lost 5 percent of the youth vote nationally (down from 60 percent to 55 percent). In Florida, Democrats’ margin of victory among the young dropped 16 percentage points. In both Ohio and Pennsylvania, the drop was 19 points. In Wisconsin, 20 points.

“It is unlikely that such significant drops were simply due to the more-liberal millennial generation changing their minds from one election to the next,” said Brauer.

“It is much more likely the precipitous drops were due to the more conservative Generation Z being able, for the first time, to express their political inclinations, especially in the economically hard-hit swing states.”
