Trump's election has changed Obama's post-presidency plans

“Obama’s post-presidency just got exponentially more interesting,” said Cody Foster, a University of Kentucky historian who has studied the post-presidential lives of former presidents.

“Whereas he might have focused on building upon policies created during his administration, he must now defend his administration’s legacy,” Foster said. “Every policy, every veto, every word must now be carefully defended against an incoming leader eager to blindly press ‘undo’ on everything that Obama created. And President Trump can do that because he has a Republican Congress and is likely to have a more conservative Supreme Court.”…

“I don’t see him immediately becoming a Jimmy Carter-like thorn in the new president’s side,” said Anthony Clark, author of The Last Campaign: How Presidents Rewrite History, Run for Posterity & Enshrine Their Legacies. “But I also think he’s going to be more critical than previous presidents have been. He’s going to have to find a way to be anti-Trump without appearing to be anti-Trump.”
