Sean Wilentz, a scholar in American history at Princeton, said many presidents have sought to frame themselves in the historical legacies of illustrious predecessors, but he couldn’t find any examples quite so brazen.

“Sure, they’ve looked back to Washington and even, at times, Jackson. Reagan echoed and at times swiped FDR’s rhetoric,” said Wilentz. “But there’s never been anything like this, and on this scale. Ever.”

Eric Foner, a Columbia historian who has written extensively on the Civil War era, agreed that comparing one’s self to Lincoln sets a rather high bar for success, and could come off like “a certain kind of hubris.”
