Millennials supported Clinton over Trump in the 2016 election by 20 points -- the biggest gap of any generation.
Moreover, the 35% who supported Trump "are less experienced in civic and community engagement ... and they are less likely to say that they would take up a formal civic opportunity (like regularly volunteering for a nonprofit organization)."
Clinton supporters, by contrast, were more engaged in civic and political life to begin with.
The Tufts study, taken just after before and after the election, thought that the high level of civic mobilization of the Clinton voters would depend on whether the Trump administration attacked "individuals and organizations with diverse viewpoints, including those of young people largely oppose him."
Now that we are almost a year after the election, I think we can clearly answer that question in the affirmative.
