A desperate America seeking distraction from an ugly political climate may have found a new sweetheart. He is Kenneth Bone, an undecided voter in a bright red sweater.

Whether that affection will last once he makes up his mind remains to be seen. In an interview with The New York Times, he revealed how he is now leaning.

Mr. Bone, 34, an operator at a coal plant in Illinois, was one of the undecided voters selected to ask a question at the town hall debate broadcast live on Sunday night.

He offered a contrast to the presidential candidates’ combative tone when he asked a straightforward policy query near the end of the 90-minute live broadcast.
