Mr. Trump is largely shunning traditional debate preparations, but has been watching video of Mrs. Clinton’s best and worst debate moments, looking for her vulnerabilities. Mrs. Clinton has a thick dossier on Mr. Trump after months of research and meetings with her debate team, including analysis and assumptions about his psychological makeup that Clinton advisers described as critical to understanding how to knock Mr. Trump off balance. Mr. Trump, in turn, is approaching the debate like a Big Man on Campus who thinks his last-minute term paper will be dazzling simply because he wrote it. Mrs. Clinton is eager to play offense and try to get under his skin, by doing things like calling him “Donald” and questioning his net worth. Should Mr. Trump confront her on the private email server she used at the State Department, she should aggressively respond by pointing to his not disclosing his tax returns.
