DETROIT — Nearly everyone agreed: The bathrooms were a problem.

Maybe not as big a problem as, say, health care or climate change. But a problem, nonetheless.

During Tuesday’s debate at the Fox Theater in downtown Detroit, the Democratic presidential candidates would be offered portable toilets in trailers. Stalls for the women. Two urinals and a stall for men. All of them accessible only by going outside, under the cover of an umbrella-holding escort, in the case of rain.

But this was only one problem in a city suddenly full of political problems.

Rick Gorka, a regional director of communications for the Trump campaign, had another problem: getting reporters to a panel discussion featuring Ronna McDaniel, the chairwoman of the Republican National Committee, a few blocks away from the debate site.
