U.S. voters sent a clear message about artificial intelligence on election day: slow down. According to Ballotpedia data and results compiled by CNBC, voters backed restrictions on data center development, or rejected measures that would have enabled it, in 40 of 41 local ballot measures across 10 states. Now that backlash has a national vehicle: the Artificial Intelligence Data Center Moratorium Act, pushed by Senator Bernie Sanders, which would pause construction and upgrades at AI data centers nationwide until Congress writes broad new safeguards for the technology.
What voters decided on Tuesday
Ohio alone decided 21 of the 41 measures, and voters sided against new development again and again. Edgewater, Florida, voted to write a ban on data centers into its city charter. The one exception was Harwood, North Dakota, where voters rejected a charter change that would have added extra review before large industrial projects, including data centers, could be approved.
The exit polls matched the ballot results. An NBC News exit poll found that 76 percent of voters would oppose a new data center in their own community, and 56 percent said AI and data centers were a crucial or major factor in their vote for Congress. The complaints behind the votes are consistent: electricity bills, water use, noise, tax breaks, and the feeling that enormous projects were approved before residents had a say. The same unease has already rattled investors in the AI buildout, but the ballot measures are the part with legal force, and they set the stage for everything now moving in Washington.
What the bill would actually stop
The bill exists in two versions: S. 4214 in the Senate, sponsored by Sanders, an independent from Vermont who caucuses with Democrats, and H.R. 9442 in the House, led by Representative Alexandria Ocasio-Cortez of New York with 20 Democratic cosponsors. Section 3 is the freeze. If it became law, the construction or upgrading of new or existing AI data centers, in the bill’s words, “may not commence or proceed,” starting the day the law takes effect, with no exception for projects already under construction.
Coverage is broader than the 20 megawatt figure in most summaries. A facility counts as an AI data center if it is used for the development or operation of artificial intelligence models at scale, and that test has no size limit. A facility also counts if it tops 20 megawatts and is built to deliver 20 kilowatts or more to a single server rack, or to cool hardware with liquid circulated to individual components or by submersion. In plain terms, the bill aims squarely at the dense, liquid cooled halls that AI training depends on.
Two key phrases are left undefined. The bill never says what counts as operating “at scale,” and it never defines “upgrading.” That leaves an everyday question unanswered: could an operator swap newer chips into an existing building, or would that be a banned upgrade? The drafting matters. In Maine, the legislature passed an 18 month state pause this year, and Governor Janet Mills vetoed it for lacking an exception for a 550 million dollar project already underway.
The export clause hiding in Section 4
The least discussed part of the bill may be the widest reaching. Section 4 directs the Commerce Department to prohibit exports of chips, computers, networking equipment and storage systems meant for AI data centers, or for training or running AI models at scale, to any country that lacks laws “comparable” to the safeguards that would end the moratorium. The bill does not explain how the Commerce Department would judge which countries qualify. Because so much advanced AI hardware is designed in the United States, an export ban tied to other countries’ AI laws would turn a domestic construction fight into a global supply question.
What would have to happen for the pause to end
The freeze has no end date: it lifts only when Congress enacts laws that expressly end it and meet a long list of conditions. Those laws would have to require federal review and approval of AI products before release, protect workers from job displacement and share the wealth AI creates with the public, keep new data centers from raising consumer electricity bills or harming the environment, let affected communities approve or reject projects, bar government subsidies for the data centers, and require union jobs at prevailing wages. Each condition is a major bill in its own right, which is the point: the moratorium is built to hold until a full regulatory settlement exists.
Why a national ban is still a long shot
For all the momentum, the federal freeze faces hard math. Democrats won Congress on November 3, but NBC News counts on November 5 showed 54 Senate seats on the Democratic side, six short of the 60 votes usually needed to end a filibuster. President Donald Trump, whose term runs to January 2029, has promised to veto measures he opposes from the new Congress, and neither House Democratic leader Hakeem Jeffries nor Senate Democratic leader Chuck Schumer has endorsed it. The bills also face a calendar problem: they were filed in the Congress that ends in January, so they would have to be introduced again in the new session. The White House backs a competing approach built on ratepayer protections, and a narrower bill in that mold, the Ratepayer Protection Act, passed the House 417 to 3 in September.
The real fight is in the states
The faster, more certain changes are happening below the federal level. CNN reported that, come January, states controlled by Democrats who support expanding or extending AI construction moratoriums will hold about 45 percent of planned U.S. data center capacity, according to Goldman Sachs. Democrats won the governor’s races in Nevada, Georgia, Ohio and Texas on campaigns promising tighter data center rules, from ending tax breaks to letting local governments impose their own moratoriums.
Texas is the biggest test. The state holds about a quarter of the country’s planned AI buildout, and Republican Governor Greg Abbott had already imposed a statewide moratorium on new data centers. Governor-elect Gina Hinojosa campaigned on extending the pause until the legislature sets stronger requirements. Unlike a bill in Congress, a state moratorium does not need 60 Senate votes, and it cannot be vetoed from Washington.
The industry is adjusting in public. On November 5, OpenAI published commitments for the data centers it owns and operates: pay the full cost of powering them, seek community input, publish construction plans and stop using nondisclosure agreements with public officials. Whether or not the Sanders bill ever reaches a vote, the permits, power contracts and zoning hearings that decide where AI gets built are now political fights, and voters intend to be heard in them.
