By the time that former President Donald J. Trump joined TikTok in June, conservative content was flourishing on the social media platform, known for its grip on young people.
Mr. Trump’s TikTok account is part of an online conservative ecosystem characterized partly by videos, streams and messaging that rail against traditional institutions and promote a cultural ideology that pushes back on social movements supporting different gender identities and diversity, equity and inclusion. That environment has had an effect on many voters, particularly members of Generation Z, for whom Mr. Trump has been a consistent presence on presidential ballots since they became eligible to vote.
