Kamala Harris made $370 million in TV and digital reservations from Labor Day to Election Day to secure cheaper prices than last-minute purchases.

The $170 million in TV buys include spots in swing states on shows like Grey’s Anatomy, Abbott Elementary School, Survivor And Golden Bacheloretteas well as the early evening classics such as Wheel of Fortune And DangerThe purchase list also includes seats at college and NFL games, WNBA and NBA, NHL and Major League Baseball.

The campaign also said the $200 million digital content purchase was the largest such spending in presidential campaign history and reflected changing consumer streaming habits.

The reservations include connected TV platforms, premium video and digital audio, including Hulu, Roku, YouTube, Paramount+, Spotify and Pandora. “We believe we are on track to spend more on digital persuasion media than any political organization ever has,” Quentin Fulks and Rob Flaherty, deputy campaign managers, wrote in a memo.

They pointed out that the Trump campaign’s TV purchases allowed it to make long-term reservations in only two states, Pennsylvania and Georgia.

“Prices increase as the air date approaches, and there is also less supply to choose from,” they wrote. “So if Trump buys later, he spends more per ad buy and gets worse ad placements, especially on high-viewership programs like live sports.”

The campaign also announced that it is buying airtime on Fox News, “particularly during daytime programming that reaches a more moderate audience.” “Our data clearly shows that the hundreds of thousands of Nikki Haley voters in swing states and other independent voters with conservative leanings are flocking to us, and we will meet them where they are,” Fulks and Flaherty wrote.

The campaign also said it is investing “a significant eight-figure amount” in national TV placements, noting that these are “less likely to run back-to-back with other political ads, which is a common problem as campaigns approach Election Day.”

The reservations come in addition to a current $150 million advertising campaign in seven swing states.
