Record $10 billion election ad blitz fuels personal attacks and AI deepfakes

In the closing weeks of the 2026 midterm race, political advertising has reached an unprecedented level, topping $10 billion through September and expected to rise further by Election Day. Republicans maintain a slight spending lead, though the gap is narrowing, and both sides focus on economic issues—Democrats highlighting groceries, gas and health costs, Republicans centering on tax relief. The ad environment is increasingly hostile, illustrated by a contentious Ohio spot where Vivek Ramaswamy’s campaign uses Donna Arthur, the estranged mother of Amy Acton, to label the former health official a liar, prompting backlash from voters.

At the same time, AI-generated deepfake ads have exploded, with roughly 220 identified and $137 million invested, predominantly by Republican groups, many lacking clear disclosure. Experts note that the blend of policy criticism, personal smears and undisclosed AI content may erode voter trust even as parties pour historic sums into the media blitz.
