President Obama is expected to use his final presidential address to the nation Tuesday night to urge President-elect Trump not to undo his legacy, a tough sell when nearly 60 percent of voters believe the U.S. is headed down the wrong track.

From the steel-and-glass interior of Chicago’s McCormick Place, where Obama celebrated his re-election victory in 2012, the outgoing commander in chief will deliver his final address to the nation after eight years of progressive policy triumphs and just as many lost opportunities for lasting bipartisan reforms. The farewell speech could be Obama’s last public appearance before Jan. 20, when he turns the White House over to Trump, who’s vowed to undo several of Obama’s executive actions and erase many of Obama’s achievements.
