Ohio voters delivered the AI industry its clearest rebuke yet on Tuesday. Across 21 local ballot measures in 18 municipalities — the most of any state — voters passed bans or restrictions on data centers in at least 14 communities, according to the Cincinnati Enquirer and Fortune. The margins were not close.
The results, town by town
Ten municipalities passed outright bans on data-center construction: Hubbard, Sunbury, Pataskala, Urbana, Defiance, Upper Sandusky, Piqua, Granville, Conneaut and Trenton, the Enquirer reported. Several more passed new regulations or voter-approval requirements.
The numbers, from unofficial county results, show how one-sided the votes were:
| Municipality | Measure | Result (unofficial) |
|---|---|---|
| Trenton (Issue 17) | Ban on facilities over 25 MW | 79.68% yes (3,541 to 903) |
| Granville | Charter ban over 25 MW | 82.45% yes (2,015 to 429) |
| Sunbury | Charter ban over 25 MW | 78.64% yes (2,809 to 763) |
| Pataskala | Charter ban over 25 MW | 73.62% yes (5,418 to 1,941) |
| Urbana | Ban over 7.5 MW | About 77% yes |
| Grove City | Voter approval required for large projects | 54.60% yes (11,317 to 9,411) |
| Ashville | Reverse EdgeConneX development deal | 81.61% no to the deal (1,469 to 331) |
In Ashville, a village of about 5,000, voters moved to reverse the council’s agreement with EdgeConneX to build two data centers and a natural-gas power plant on 195 acres. In Trenton, the vote clouds the future of an Amazon Web Services campus planned just outside the city — and the St. Clair Township Zoning Commission has already passed a resolution to ban data centers in the township, with a county hearing set for November 10. In Piqua, voters both passed a data-center ban and recalled three city commissioners.
A national pattern
Ohio was the epicenter, but not the exception. Voters in 10 states faced 41 data-center measures on November 3, according to a Ballotpedia count, and by Wednesday 33 local measures restricting data centers had passed or were leading, Stateline reported, citing the Data Centers on the Ballot tracker. A yes vote on 28 of the 41 measures would limit data centers; the other 13 would help them get built.
The votes sit on top of a backlash already underway: Ohio already had 125 local moratoriums on data centers, with more than 200 operational sites and $40 billion in planned company investment through 2030, according to Fortune. A statewide poll found 55% of Ohio adults opposed data-center construction and 22% in favor, with 65% opposed to tax breaks for the industry.
Why it matters beyond Ohio
The results landed the morning after an election in which data centers became a statewide issue: in the Ohio governor’s race, both major candidates promised tougher conditions on new facilities, and the governor appoints the five members of the utilities commission that sets electricity rates and data-center terms. Elon Musk weighed in on Wednesday, writing that data centers in space were looking “appealing” after the midterm results.
All of Tuesday’s totals remain unofficial. The Ohio Secretary of State says certified results will be published approximately three weeks after the election.
What to watch next
Watch the certified results in about three weeks, the November 10 county hearing on the Trenton-area AWS campus, and whether state lawmakers — or the next governor — turn the local bans into statewide rules. The industry’s $40 billion Ohio pipeline now runs through towns that have just voted, overwhelmingly, to slow it down.
