One more crowded-stage debate probably won't do much but it is a major event in Iowa and it's part of a regimen all had agreed to.
The Donald Trump campaign had hit a stride lately and the businessman seemed to be locking down a lead even opponents said was daunting.
The fight Trump picked with Megyn Kelly does seemed to have rattled her. She looked it last night on her show, but it's really not about some anchor.
The Trump gambit is about publicity and about protecting a lead.
I would show up as holding a competing event looks petulant. Then again, maybe the self-absorbed cable media need some humbling.
Who knows, other than this flap will be forgotten by Saturday.
