US campaigns are baking AI into every step of the process, and Europe is pushing back with the AI Act

US Campaigns Embed AI in Every Step as Europe Pushes Back With the AI Act

AI is now baked into every phase of US political campaigns — from voter targeting and ad creation to real-time response optimization. Meanwhile, Europe’s AI Act imposes strict transparency and risk management rules that could reshape how these tools cross borders.

The 2024 US election cycle has become a laboratory for artificial intelligence. Campaigns use generative AI to draft fundraising emails, create synthetic ads, and personalize outreach at scale. Europe, wary of disinformation and privacy violations, is responding with the world’s first comprehensive AI regulation.

AI’s Role in Campaign Strategy is Expanding Rapidly

Microtargeting voters is the most common use. AI models analyze demographic data, browsing history, and past voting behavior to predict which messages will sway specific individuals. Tools like ChatGPT or custom LLMs help write thousands of unique email variants in minutes.

Synthetic media production is also surging. AI-generated images and voice clones appear in ads that test messaging before human creators finalize them. Some campaigns deploy chatbots to answer voter questions on websites — often without disclosing the bot’s non-human nature.

“Campaigns are moving faster than regulators can keep up,” a digital strategy consultant told The Decoder. “The question is whether voters will know they’re being interacted with by a machine.”

The EU AI Act: Europe’s Countermove

Risk-based classification is the AI Act’s core. Systems used in political campaigns that profile individuals or influence elections will likely fall under “high-risk” categories. This triggers mandatory transparency, human oversight, and bias testing.

Transparency obligations are strict. Any AI-generated content intended to influence public opinion must be labeled. Voters must be told when they are speaking to a bot. Campaigns using AI to target vulnerable groups — such as age-based or health-related profiling — could face fines up to 7% of global annual turnover.

Enforcement challenges remain. The Act applies to any AI system used within the EU, even if developed elsewhere. US campaign firms operating in Europe — or handling European user data — will need compliance frameworks.

Where the Two Approaches Clash

Data access is a flashpoint. US campaigns rely heavily on vast data sets from social media platforms and data brokers. The AI Act restricts the use of sensitive personal data for profiling without explicit consent, a major hurdle for American-style microtargeting.

Content moderation differs starkly. US platforms rely on voluntary measures and Section 230 protections. The AI Act imposes legal liability on platforms for high-risk AI outputs, effectively forcing them to police campaign-generated content more aggressively.

Cross-border election interference is a new frontier. A US campaign using AI to influence EU voters — for example, through targeted ads about Brexit or migration — could be investigated under the Act, creating diplomatic tension.

What This Means for Campaigns Worldwide

Non-EU campaigns must adapt if they target European audiences. That means auditing AI tools for bias, adding labels to synthetic content, and maintaining documentation of model training data.

The US is unlikely to follow Europe’s lead soon. The Federal Election Commission has so far declined to regulate AI in campaign ads beyond existing disclosure rules. Industry groups argue that voluntary guardrails are sufficient.

Tech companies face a patchwork of rules. A single AI ad tool might need to comply with the AI Act in Europe, state-level laws in the US (like California’s bot-disclosure law), and voluntary pledges elsewhere.

“The AI Act is the first serious attempt to govern political AI globally,” said a Brussels-based policy analyst. “But its real test will be enforcement — and whether campaigns can innovate faster than regulators can react.”
