Democrats maintain overall lead in presidential ad spending

 To date, Democrats have outspent Republicans on ads overall and in the swing states, and Democrats also have the edge in future bookings.

Since President Joe Biden dropped out on July 22, the presidential race has seen almost $950 million worth of advertising, and Democrats lead by about $563.5 million to $380.2 million, according to data from AdImpact.

The split is closer in the swing states, where there’s been $762.6 million worth of presidential advertising since Biden dropped out, and Democrats lead by about $418.5 million to $340 million.

Emphasis on digital ads: A big part of Democrats’ overall edge is their commitment to digital advertising. Outside of the swing states, the Harris campaign and its allies have plowed more than $100 million into digital advertising, much of it aimed at online fundraising, powering a record-breaking fundraising surge. Over the same period, Republicans have spent about $27 million on digital ads.

Looking ahead, Democrats have more than $325 million in total remaining advertising reservations, with $281 million of that targeting the seven key swing states. Republicans have about $185 million worth of total remaining ad time booked, virtually all of it in the battlegrounds.

Pennsylvania dominates the lists of both states that have seen the most ad spending so far, and states with the most ad time remaining. The parties have already combined to spend more than $200 million in the commonwealth since Biden dropped out, Democrats leading by about $113 million to $91 million. And $129 million worth of presidential advertising remains to air in Pennsylvania, Democrats with $74 million left booked, and Republicans with $56 million.
