Increasingly active younger voters liberalize U.S. electorate

For the first time, the millennial generation and Generation Z combined to make up a greater share of the electorate than Generation X.

And more of those younger voters are getting more comfortable casting their ballots: Among those between the ages of 30 and 39, almost half are frequent voters, up from just over a third four years ago, a sign that a generation long dismissed for its apathy is engaging in politics more habitually.

There are signs that the emerging younger electorate is likely to provide a windfall for Democratic candidates. In states where voters are allowed to register by party, 52 percent of voters 18 to 29 are registered Democrats, compared with just 35 percent who are registered Republicans. Among 30- to 39-year-olds, the gap is even wider: 53 percent are registered Democrats, while just 34 percent are registered Republicans.

“Young voters were a critical component of the Democratic coalition that formed the Blue Wave in 2018, and will be perhaps even more central to Democratic hopes in the 2022 midterm elections,” Bonier said.
