She ends saying she hopes younger journalists recognize the important role of journalism in democracy. Thomas doesn't make it too clear as to what that role is. Unless that role is to get close to the president.
Thomas mentions "legwork" at the beginning of the chapter. I think this "legwork" she mentions should have been emphasized more. You don't always need to talk to the president to get the real story. Actually, a president is more likely to "spin" the story to maintain his image. If journalists spends all their time trying to get close to the president it is likely they will miss the real story. Journalists aren't groupies or at least they shouldn't be.

She looks kind of scary.
