Many who may have missed the second presidential debate on Sunday are probably wondering about the man in the red sweater, with the glasses and mustache. His name is Ken Bone, and he has become the most popular private figure in the country.

Bone attended the debate in St. Louis, Missouri, as an undecided voter who was seeking a better understanding of the candidates. He asked Hillary Clinton and Donald Trump about their energy policy during the town hall-style forum.

“What steps will your energy policy take to meet our energy needs while at the same time remaining environmentally friendly and minimizing job loss for fossil power plant workers?” asked Bone asked with a large grin.

Bone, 34, is an operator at a coal plant. His wife is named Heather and they have a 12-year-old son, Logan. The family lives in Belleville, Illinois.

His natural charisma has endured him to millions and made him an internet and television sensation. Bone has been seen on "Jimmy Kimmel Live" and several TV news programs in recent days. Each time he turns up on national television, he wears the red sweater.

"One-man basket of adorables," is the way Trevor Noah of "The Daily Show" described Bone.

By his own admission, Bone had seven Twitter followers before the debate. He now has 146,000.

“When I got back to my car and turned it on, I had 423 Facebook friend requests,” he said to the Associated Press.

Bone confirmed he will vote, though he remains undecided.
