Trump just sad that probably he won’t do the debate. Steve Sanctimonious Hayes dissing Trump.
What are any possible pitfalls of doing it? Lose composure. Flub an answer. Give the appearance of a cave to a MSM outlet.
Is there any benefit to skipping it? Yep. Giving a middle finger salute to a MSM outlet. Leaving the harpy without her target. Standing on principle.
Drawbacks to sitting out? Being called chicken by people rooting for his downfall anyway.
So I'd say sit this one out. Or as a compromise, attend after conformation that the bloody wench will be "moderating" the undercard debate.
