Thom Tillis Ducks Out of WRAL Senate Debate

Why would the supposed front-runner in the Republican primary for U.S. Senate, a supposed front-runner who is stuck at 20% in most polling, decide to forego a major televised debate with his chief rivals? (Reference: "Thom Tillis To Skip Major GOP Primary Debate")

a. He's afraid of a high-profile misstep (the WRAL interrogators ain't patsies!).

b. He's so got this race in the bag that he can afford to exhibit his native hauteur.

c. He doesn't want to dignify the clown show running against him by being photographed with them.

d. He really does have a "scheduling conflict" that he simply can not get out of (those expensive haircuts take advance planning, bitches!).
