kamala has obviously hired zoomers/soyllennials to be her campaign strategists. the "trump is weird" line is a tiktok soyllennial attempt to "bully" trump.
it's not really any different from soyllennial women calling you a small-dicked incel, it's just less vulgar and obscure and therefore more mainstreamable. tbh "creepy" might've been more effective than "weird," and i'm not really sure why they didn't go with that instead.
if they really wanna go with a kiwifarms/metokur-like strategy, they could constantly refer to trump as a "sex criminal"
they have done stuff like this before: "trump has small hands," "pee-pee tape"
