The Biden re-election campaign's decision to join TikTok is linked to poll findings indicating the president's struggle to connect with young TikTok users, despite their Democratic leanings.

Recent NBC News poll results show young TikTok users, who predominantly identify as Democrats, narrowly favoring Donald Trump over Biden in a hypothetical election, revealing a significant challenge for the Biden campaign. This contrasts with young voters who don't use TikTok, illustrating the campaign's strategic move to address this demographic's preferences via TikTok.
