Maine Senate Race: Data Centers and Billionaire Spending

The cost of living and the future of the state's power grid have become the central questions of the 2026 Senate race. In Maine, voters face a choice between two candidates in a contest that has drawn record levels of outside funding. The issue driving the debate is the rapid expansion of artificial intelligence data centers, which rural communities view as a strain on local resources. This tension has turned the election into a referendum on the tech industry's footprint in the state.

The conflict escalated in April when the state Legislature passed a bill to impose the first statewide moratorium on large data centers. Governor Janet Mills vetoed the measure ten days later. Since that veto, local towns have adopted temporary bans or placed the question on November ballots. A September poll by UMass Lowell and YouGov found that 76 percent of Mainers oppose building a data center in their community, with 58 percent expressing strong opposition.

The financial stakes are high. Democrats are projected to spend $81 million, while Republicans will spend $114 million. This total makes the race the most expensive per capita in U.S. history. A significant portion of that money comes from the data center and AI sectors. Molly White, who tracks tech spending through Tech Influence Watch, notes that the industry is using a strategy similar to the one employed by cryptocurrency backers in 2024. She observes that AI is now a frequent topic in political events, alongside traditional concerns about the economy and foreign policy.

Maine offers specific advantages to data center developers, including cheap land, vacant industrial buildings, and ample water access from its rivers. These factors attract major tech companies and private equity firms. However, the economic promise of job creation is often questioned. Economic research suggests that data centers create little net employment once construction is finished. Mark Brewer, a political science professor at the University of Maine, points out that the state has a history of extractive industries like timber and paper. While those sectors employed thousands, data centers do not offer the same level of long-term labor.

Republican incumbent Susan Collins, 73, has received substantial support from tech donors. She chairs the Senate Appropriations Committee and has secured $6.2 million in federal funding for a high-performance computing hub in central Maine. Her donors include Alex Karp of Palantir and Marc Andreessen of Andreessen Horowitz. According to White’s tracker, Collins has received $325,644 from AI and crypto donors. Nearly 100 billionaires have contributed to her reelection bid. Her family also holds financial ties to the sector, with Forbes ranking their household fifth in the Senate for AI-linked investments.

Super PACs have amplified the spending. The Republican Senate Leadership Fund, which received $158 million from Elon Musk this summer, has spent nearly $42 million on ads in Maine. Musk’s America PAC has spent approximately $2.1 million in the state. Pine Tree Results PAC, which has personal ties to Collins and her husband, has spent $29.1 million. Stephen Schwarzman of Blackstone donated $2 million to that group. A recent Federal Election Commission report shows that SpaceX’s PAC gave $55,000 to Collins’ Victory Committee in August and another $50,000 to Pine Tree Results.

Democratic challenger Troy Jackson has filed Federal Election Commission paperwork that shows no obvious ties to data centers or Big Tech, though it lists at least four billionaire donors. Jackson, a former logger, has focused his campaign on placing guardrails on AI development and ensuring union jobs for data center maintenance. He and his wife hold assets worth between $147,000 and $430,000, a fraction of Collins’ reported holdings of $4 million to $10 million.

Voters in rural areas are skeptical of outside money. Nicholas Jacobs, director of the Public Policy Lab at Colby College, explains that Mainers have a long-standing wariness toward extractive economies. He notes that while rural wealth exists, it is often moved out of the community, creating a fear of exploitation. Brewer suggests that the sheer volume of spending may backfire, causing voters to punish Collins for her associations with unpopular tech billionaires. With broadcast television inventory sold out, campaigns are shifting funds to radio, social media, and direct mail, pushing the volume of advertising to high levels.
