The Fight for Serious AI Regulation Just Won a Big Victory in Massachusetts

After his primary win, Ed Markey says he’s ready to take on “the criminal enterprises” of Big Tech.

Massachusetts Senator Ed Markey won a major primary election victory on Tuesday, claiming another win for the left in this summer’s struggle for the soul of the Democratic Party. “Tonight is a testament to the power of the progressive movement,” Markey declared to a cheering crowd in which his young supporters celebrated a 65–35 triumph over his primary rival, US Representative Seth Moulton.

It was also, the senator explained, a victory in the fight against what he described as “the criminal enterprises of Big Oil and Big Tech.” A longtime foe of corporate greed and monopoly, Markey made stymieing the plans of AI oligarchs a crucial part of his campaign. With progressive-populist enthusiasm, he promised to “tax the rich, block the bombs, and stop data centers from polluting our communities.”

This is not a new fight for Markey. As the senator noted earlier this year, he’s been “working for more than a decade to propose commonsense policies to take back unchecked power from Big Tech and put it into the hands of the American people.”

But what made Markey’s victory notable was that, in the last days of the primary campaign, he faced and overcame a cynical attack from Moulton, who attempted to dumb down the AI debate in a way that he thought would turn voters against the incumbent.

Moulton’s primary challenge to Markey was always tough to fathom. A middle-aged congressman with limitless ambition but finite political skills—as evidenced by his failed bid for the 2020 Democratic presidential nomination—Moulton tried to make the fight a generational struggle between a 47-year-old rival and an 80-year-old incumbent. The message never got traction because Markey campaigned relentlessly as an energetic progressive legislator with a record of standing on the right side of history.

Yet Moulton’s desperation to make the race a referendum on youth-versus-age made the last days before Tuesday’s primary contest an instructive measure of the emerging discourse over AI regulation.
