Take a look at the wording of
this WaPo headline:
"Obama Suffers Most From Year of Turmoil, Poll Finds."
Accompanying it is this photo:

The article goes on to describe the precipitous decline in Obama's standing in approval polls:
His position is all the more striking when compared with his standing a year ago, as he was preparing for his second inauguration after a solid reelection victory. That high note proved fleeting as the president faced a series of setbacks, culminating in the botched rollout of his Affordable Care Act two months ago.
Some may think reporters and editors are simply clumsy or indifferent writers, and sometimes they are. But much of the time they choose their words (and photos) with exquisite and subtle care. They also realize that most people only look at the headlines and photos of most articles, and that those are therefore the most important elements, and that even people who do read the article often read only the first few paragraphs.
In this
WaPo article, the headline and photo have been chosen to suggest that Obama is a suffering victim---in fact, the greatest victim---of a series of unfortunate circumstances that have befallen him. He's nearly a martyr. And the text (the excerpt quoted above is the second paragraph in the piece) reinforces that idea by this phrase, "faced a series of setbacks." Passive voice; no actor.
