Says the Milwaukee Journal Sentinel, which doesn't say where or when. There's absolutely zero information that would give us a chance to see this debate, in a post that's been up for more than 3 hours.
In the comments: "Nice writing JS, you might want to put a where or when in your story." And: "The debate will be at 7PM tonight at the Clocktower motel in Rockford,Il." Ha ha ha.
Here's the Cap Times. It says the debate will be at the Madison Concourse Hotel. I still don't know what time.
