From Real Clear Politics:
Democrats credited turnout and engagement from diverse coalitions for statewide election wins this year, but chief among these reasons was the increased participation and a large shift in support from a demographic that bedeviled the party last year: millennials.
Though Hillary Clinton won more young voters than President Trump, she underperformed with the group compared to President Obama’s elections, including lower-than-expected support in key swing states that helped Trump win. A year later, in a large part in response to Trump’s victory, surging youth turnout helped Democrats win key statewide races, and the party is counting on similar results in next year’s midterms.
Republicans generally dismiss the notion that Democratic wins in 2017 represented a pattern, arguing that Alabama’s unique circumstances and Virginia’s increasingly blue electorate are not indicative of a cresting wave of young, Democratic support.
Yet despite the unique nature of Alabama’s Senate contest on Tuesday — a controversial Republican nominee losing in a deep red state on an Election Day squeezed between two major holidays — Democrats saw encouraging signs among young voters.
“You’re really seeing millennial voters really leading now and millennial voters really taking the reins of this democracy and starting to drive it in the right direction,” said Sen. Cory Booker of New Jersey, who rallied with Democrat Doug Jones in Alabama the weekend before the election.
