The stranger: Barack Obama in the White House

Introduction: The stranger

A not-so-fresh start

Getting rolled early

Unplanned legacy

Triage

Reluctant warrior

The re-election begins ... sort of

The winter thaw

The veep steps up

Coming around on Clinton

The hunt begins

Trump, bin Laden, and the craziest week of the presidency

The Chief Executive learns to manage

A challenger emerges

If he had a son

They were first-graders

The lost year

A thick red line

Control-alt-delete

The legacy.
