The Kamala Harris and Donald Trump campaigns are releasing several new ads this week as the presidential race enters its final sprint.

Here’s a summary of the new spots hitting the airwaves, and some data on how the overall tone of both parties’ messages compares:

Positive versus negative messages

Ads from the campaigns and their allies cover a wide range of competing issues, and also reflect varying strategies when it comes to their overall tone.

The ad tracking company AdImpact categorizes the tone of campaign ads airing on television as “positive,” “negative,” or “contrast.” Comparing the share of each party’s spend that goes to ads of each tone illustrates how advertisers divide their messaging budgets.

And the data shows that the Trump campaign and its allies are waging an overwhelmingly negative advertising effort. By comparison, data on the Harris campaign and its allies reflect a more balanced approach.

New campaign ads for Trump

Trump’s presidential campaign has launched five new TV ads so far this week, making a wide range of criticisms of Harris.

Nearly all of the ads reference immigration and border security, criticizing Harris’ record and linking illegal immigration to other issues, including crime, rights and transgender health care policy — a major focus of the Republican Party’s campaign ads so far in October.

One of the notable new spots is Harris’ comment on “The View” last week, when she was asked how she should govern differently than President Joe Biden and responded that “nothing comes to mind.”

New Harris campaign ads

On the other hand, the Harris campaign has delivered a massive wave of thirteen unique new TV ads so far this week, maxing out its priceless financial advantage in the final sprint of the race.

The ads reflect a varied approach, combining spots that promote and contrast Harris’s policies with Trump’s, alongside a steady diet of sharp attacks – and they also display a highly tailored strategy, with several spots focusing on important swing states, with local voters and problems.
