Over all, 59 percent of people 18 to 24 say they’re Democrats, compared with 33 percent who say they’re Republicans, according to an Upshot analysis of Pew Research Center data over the last year. Even young people who self-identify as Republicans, another Pew survey found, say they hold more liberal views than older Republicans on a wide range of issues — including race relations, the causes of climate change and the involvement of government in people’s lives. The youngest Republican voters who supported Mitt Romney in 2012 were the most likely to abandon Mr. Trump in 2016.
The youngest white voters are more evenly split between parties. About half of whites ages 18 to 24 say they’re Republicans. They favored Mr. Trump in the presidential election, but those who turned out in the midterm elections very narrowly backed Democrats, according to preliminary data from Catalist, a Democratic data firm. And only 39 percent of 18-to-24-year-old whites approve of Mr. Trump, the Pew data shows.
Also, this next generation (those born after the mid-1990s, the so-called Generation Z) will be the first in which nearly half of the electorate is nonwhite — a group that overwhelmingly votes Democratic.
