Thin with a boyish face and earrings in both ears, 23-year-old Isayah Turner does not look like a stereotypical Trump supporter, who tend to be middle aged or older.

Nevertheless, Turner drove two hours from his home outside Milwaukee on a recent Tuesday to see Republican presidential candidate Donald Trump at a rally in Green Bay, Wisconsin, one of a contingent of young voters there that some opinion polls suggest could be a growing and important demographic for Trump.

For Democratic incumbent Joe Biden, who overwhelmingly won the youth vote in 2020, an erosion of his support among young voters could potentially dampen his hopes of a second term.
