Rob Sand, the Democratic candidate for Iowa governor, has recently rolled out a plan to restrict data centers. His proposal would end state tax breaks, require more disclosure, and add consumer protections, citing concerns about water use, electricity demand, secrecy, and local impacts. He is also in the general election against Republican nominee Zach Lahn. Earlier, Sand said an audit of Iowa Medicaid pharmacy benefit managers suggested taxpayers may have been overcharged, though his office said missing records limited how fully it could measure the impact.
