One of the most fiercely contested battlegrounds in this fall’s presidential race won’t remove more than 4 million ineligible names from its voter rolls. 

“Wisconsin’s population is a little less than 6 million, with 3.5 million active voters,” Sen. Ron Johnson, R-Wis., told The Daily Signal in a written statement. “So why do election officials refuse to clean up Wisconsin’s voter rolls and [instead] allow up to 4.1 million inactive voters to remain, with the potential for fraudulently using those names?”

Although Johnson and some other lawmakers contend that unpruned voter rolls create election security holes, the Wisconsin Elections Commission contends that it ensures proper recordkeeping and prevents fraud. 

A website of the Wisconsin Elections Commission called Badger Voters numbers “all voters” in the state at 7.7 million. That’s a total of 3.5 million active voters and 4.19 million inactive voters.
