Trump's seat of the pants style wearing thin
One of the reasons Trump is avoiding debates is that he can't defend his proclamations. It would be a mistake to call them policies at this point because they do not have much thought beyond his own whims. It is one of the reasons why he lashes out at opponents with insulting names and bogus charges to distract from his lack of substance.
None of Donald Trump’s tune changes seemed to matter much until recently. But his style — long on gut instincts, short on briefing books — has taken a toll.
