Ronna. McRomney.
I doubt she has the authority to make that decision on her own. I'll bet it was the same members of the Republican National Committee that elected her earlier this year to continue running the show.
Wisconsin was one of the States where Trump said voter fraud occurred in 2020. He won Wisconsin by a narrow margin in 2016, and Biden won it in 2020 by less than 21,000 votes. Wisconsin then went after 10 individuals they claimed were fake electors for Trump, and settled a civil lawsuit with them recently. So why would the RNC hold its convention there when there was so much BS with the State in 2020? To me it's just another example of the GOP stabbing Trump in the back. Milwaukee is in a blue county, so I'm sure there will be plenty of BLM and Antifa protesters taking advantage of the convention being held there.
