Down deep, Trump surely knows he owes his presidency to Clinton. His vulnerabilities as a candidate were precisely the spots where Clinton was too weak to land a blow. The murkiness of his finances was offset by the shadiness of the Clinton Foundation. Her outrage at Trump’s boorish behavior rang false given her infinite tolerance for her husband’s. If Trump’s first impulse was always to dodge the truth, well, where had we seen that before? Clinton had to collapse in public before she was willing to admit to a mild case of pneumonia. Her story about her emails had more holes than Trump National Golf Club. As for the empty slogans of his campaign (“Build that wall”), they were hardly less substantial than hers (“Stronger together”). His ignorance of policy and history demanded a campaign about nothing. She gave it to him.
