From Ann Althouse's review of "Shattered: Inside Hillary Clinton's Doomed Campaign."

Even Hillary's Debate Practice Opponent Knew Trump Could Beat Her Given His Superior Messaging 

 67% of the way in: "But [Hillary] accepted the conventional wisdom that she could win or lose the presidency based on her performances [in the debates] against Trump — a rival who thrived on getting under the skin of an opponent. And what [Phillippe] Reines found, [playing the role of Trump] as he practiced against her, round after round, is that Hillary’s heavily nuanced policy arguments were boring and easy to pick apart with a sharp retort. Her strength and her weakness were one and the same: she mastered so much material. 'As the guy who would kick her ass over and over again,' it was obvious to Reines that Trump’s messaging was better, said a source with singular knowledge of his thinking.... [H]er stiffness and her inability to reply to specific questions with thematic answers... were painfully obvious in the debate-prep sessions. Reines had been able to exploit them and outperform her. Heading into the first debate.... Hillary and her team were nervous that Trump might do the same thing. " 

I think everyone knew this but no one, particularly the liberal media, wanted to say it
