Data center votes draw scrutiny in Wisconsin campaigns

Past legislative action on data centers is becoming an issue for Wisconsin incumbents in both parties, with campaign advertising focusing on the state’s tax treatment and regulation of the industry.

The messages appearing on television, streaming services and online blame state lawmakers for making Wisconsin more welcoming to large technology companies and hyperscale data centers. These facilities are the focus of renewed attention to earlier votes as legislative candidates face questions about their records.

One lawmaker named in advertising

State Sen. Howard Marklein, a Spring Green Republican, is among the lawmakers targeted. An ad from the Democrat-aligned Wisconsin Ideas Project accuses Marklein of giving too much to data center developers.

The criticism connects Marklein to the broader debate over whether Wisconsin’s approach offers excessive benefits to data centers. It also shows how votes taken before the current campaign can become central to political advertising when projects and their effects receive new attention.

The policy dispute

The issue centers on past legislation involving data center tax incentives and regulations. Campaign messages are using those decisions to question how incumbents handled the balance between encouraging economic development and setting state rules for the industry.

The advertising does not settle the policy question. Voters weighing the claims can focus on the specific legislation involved, what each measure changed and how individual lawmakers voted. Further campaign activity could show which additional incumbents are challenged over their records and whether candidates offer new positions on data center incentives or oversight.
