WASHINGTON — Joe Biden’s Democratic presidential campaign is reserving $280 million in digital and television ads through the fall, nearly twice the amount President Donald Trump’s team has reserved.

The Biden campaign announced in a Wednesday memo it’s reserving $220 million in television airtime and $60 million in digital ads, in contrast to the $147 million the Trump campaign has reserved, according to a review of Kantar/CMAG data by The Associated Press. Both campaigns can add to or subtract from their reservations at any time.

Biden, the presumptive Democratic nominee, is reserving airtime in 15 states, which includes a number of traditional swing states — Pennsylvania, Michigan, Wisconsin and Florida — as well as a number of historically Republican states, including Arizona, Georgia and Texas, and a few traditional swing states that seemed to be moving away from Democrats in recent years, such as Ohio and Iowa. His campaign says a “significant portion” of the reservation will be minute-long ads.

It’s part of an effort to solidify what Biden aides say are the multiple paths to an Electoral College victory open to Biden heading into November. The campaign says it will continue to drive home a message focused on what it says is Trump’s lack of leadership on the coronavirus and that it sees Biden as the best messenger in the ads.

“We think it’s important that people see him, and hear him, because it goes to the issue of leadership, and the kind of reassuring presence and stable leadership which we believe people see in Joe Biden,” said Biden senior strategist Mike Donilon.

But campaign aides said Biden’s vice presidential pick, whom he’s expected to announce next week, will have a “robust presence” on the campaign, including advertising.

On digital, the campaign is reserving ads on streaming services like Hulu, YouTube and ESPN, as well as podcasts and mobile and online gaming platforms.

The campaign also plans to launch an “unprecedented” paid media campaign to educate voters on their options for voting, heading into an election year when record numbers of voters are expected to vote via mail due to the coronavirus pandemic and new registration and voting requirements and options have cropped up.
