Political commentators have already dubbed them the “Kamala Power Couple,” suggesting that their combined reach could sway a significant number of young voters—especially those who may not have been particularly engaged in politics before.

Unsurprisingly, Kelce’s endorsement didn’t sit well with everyone. Fans of the Kansas City Chiefs took to social media to express their dismay, some even questioning whether Kelce’s political stance could affect his performance on the field. One disappointed fan tweeted, “Stick to football, Kelce. We didn’t sign you to make political statements.”

Meanwhile, supporters of Harris couldn’t contain their excitement. One user posted, “If Travis Kelce is endorsing Kamala, then she’s got my vote. Football and politics are the crossover event I didn’t know I needed!”
