In a memo Saturday, the Harris-Walz campaign indicated $170 million in television reservations would begin hitting the critical swing states after Sept 3.

A remaining $200 million would be allocated for use on digital platforms including Hulu, Roku and YouTube.

The campaign is looking to maximize impact by broadcasting on high viewership — and expensive — sporting events and television premieres, according to the memo.

Ads will also run on Fox News in an effort to win GOP-leaning voters who remain skeptical of Trump.

While former president Trump led Biden in the money race during the summer, Harris’ ascension to the top of the ticket has unlocked hundreds of millions in new donations, putting Democrats at a significant cash advantage during the campaign’s home stretch.

Trump’s comparatively cash-strapped operation has only reserved advertising time in Pennsylvania and Georgia after Labor Day, according to AdImpact, a media tracking firm.

Recent polls show a tight race between Trump and Harris in all the major battlegrounds, but the former president scores consistently higher on the issues of immigration and the economy — both of which will likely significantly impact the final outcome.
