Wisconsin Rep. Tom Tiffany will run for governor next year, he announced Tuesday, joining a growing Republican primary for the open governorship in the battleground state. But under Democrat leadership in Madison, that dream is slipping away,” Tiffany said in a video announcing his campaign. Tiffany, who is in his third full term representing the 7th District in northwest Wisconsin, is seeking to succeed retiring Democratic Gov. Sara Rodriguez, Milwaukee County Executive David Crowley, state Sen. Kelda Roys and state Rep. Francesca Hong. Tiffany also said he would freeze property taxes as governor and work to stop China from buying farmland in the state.
