For a fine example of media bias in action, see this New York Times article on Donald Trump's fondness for "junk food":
Mr. Trump's presidential campaign is improvised, undisciplined, rushed and self-indulgent.
And so is his diet....
He prefers burgers and meatloaf, Caesar salads and spaghetti, See's Candies and Diet Coke. And he shuns tea, coffee and alcohol.
How is shunning tea, coffee, and alcohol — or for that matter, even choosing to drink Diet Coke rather than the full-calorie version — evidence of being "undisciplined...and self-indulgent"? The Times doesn't say, probably because the Times would find some way to hurl insults at Mr. Trump no matter what he eats or drinks. The underlying reality has no bearing on what the paper writes.
For example, the See's Candies are owned by Warren Buffett's Berkshire Hathaway, which also has a large investment in Coca-Cola stock. When Mr. Buffett endorses and campaigns with Hillary Clinton, the Times doesn't describe him as a "junk food" profiteer, or fault her for associating with someone getting rich from self-indulgence.
The Times article refers for comparison's sake to the eating habits of other politicians, including Barack Obama, George W. Bush, John Kerry, and John Kasich. The one politician mysteriously omitted from the article is Bill Clinton, who, like Mr. Trump, was fond of McDonald's and french fries.
