"Defend American Jobs" was the PAC splashing out in the Utah race. They're the Republican-focused crypto super PAC; "Protect Progress" is the Democrat counterpart.
Though Fairshake (nominally nonpartisan, and by far the highest fundraiser of the crypto PACs) previously made identical donations to both, they've just made another $5M donation to DAJ without a corresponding donation to PP.
DAJ has raised $14.7M so far this cycle; PP $10.3M.
