Hillary Clinton committed weeks ago to the general-election presidential debates. Donald Trump has yet to officially sign on. One reason for the holdout: "I'll have to see who the moderators are," Trump told Time magazine last month. "Yeah, I would say that certain moderators would be unacceptable, absolutely." As of Friday, the lineup was out: NBC's Lester Holt will moderate the first debate Sept. 26 at Hofstra University in Hempstead, N.Y., ABC's Martha Raddatz and CNN's Anderson Cooper will lead a town-hall-style forum at Washington University in St. Louis on Oct. 9, and Fox News Channel's Chris Wallace will handle the questioning at the final debate Oct. 19 at the University of Nevada in Las Vegas. So, are these journalists acceptable? Will Trump debate?
