Kamala Harris' campaign has launched a series of advertisements aimed at appealing to young men, including the first political ad on DraftKings, the popular sports betting platform.

DraftKings, which has around 18 million monthly visitors in the US, is largely used by men aged 35 to 44. The campaign also announced plans to run digital ads on Yahoo Sports, which attracts a primarily male audience and receives 405 million monthly views, according to The Hill.

In addition to targeting sports betting sites, Harris’ campaign is also reaching out to male audiences on platforms like IGN and Fandom, per The Hill. The campaign has enlisted prominent figures such as former NBA star Magic Johnson and actor Ben Stiller to voice their support.

The push seems to reflect concerns within the Harris campaign over a lack of male support. In recent days, Harris' running mate Tim Walz has been tasked with broadening outreach to male voters. Walz participated in a publicity stunt hunting trip and even held a rally in Arizona alongside a World of Warcraft Twitch streamer.

Additionally, the pro-Harris “Beige Rainbow” PAC, which has been pushing the “White Dudes for Harris,” initiative released an advertisement last month telling white men that they are “the problem” in America. The advertisement, predictably, was met with backlash with many users on social media condemning the advertisement as being insulting towards men.

Polling data seems to underscore the Harris team’s male concerns. An October NBC poll showed Trump leading Harris 56 percent to 40 percent among male voters. A separate AP poll found that Hispanic males are more inclined to vote for Trump than Harris. Harris has even been losing support among black men who are showing more support for the GOP nominee than they have in previous elections, a troubling sign for Harris who is relying heavily on the black vote.
