I agree with FAIR that it is outrageous that any news outlet could be announcing what candidates are "serious" or "electable" prior to any vote being cast. Bernie Sanders is being attacked whenever a media outlet concerns itself with money rather than a candidate's ideas. FAIR considers Sanders' views on many big issues, pointing out that his views are far more popular than those of conservative Republicans, whose "electability" is rarely questioned, merely because they have lots of wealthy supporters. Here are some examples from the FAIR article, "NYT Reports Large Crowds for Sanders in Iowa--but Isn't He 'Unelectable'?":

It sounds like it’s the New York Times that’s hoping to persuade Democrats that Sanders is unelectable. As we’ve noted (FAIR Blog, 4/20/15), the idea of raising the taxes of the rich is quite popular with the US public. Gallup has been asking folks since 1992 how they feel about how much “upper-income people” pay in taxes, and 18 times in a row a solid majority has said the rich pay too little. For the past four years, either 61 or 62 percent have said the wealthy don’t pay enough; it’s hard to figure why Iowans would conclude that Sanders is “unelectable” because he takes the same position on tax hikes for the wealthy as three out of every five Americans. Meanwhile, the position that upper-income people pay too little in taxes has never been endorsed by more than 15 percent of Gallup respondents—and it’s usually 10 percent or less. Yet you won’t see the New York Times declaring Republican candidates “unelectable” for advocating tax cuts for the wealthy. Cutting the military budget isn’t as popular as taxing the rich, but it’s by no means unpopular. It’s not a question pollsters often ask about—almost as if levels of military spending aren’t seen as a fit subject for public debate—but in 2013 Pew asked which was more important, “taking steps to reduce the budget deficit or keeping military spending at current levels.” Fifty-one percent said reducing the deficit; only 40 percent chose maintaining the military budget. In February 2014, the last time Gallup polled on whether spending “for national defense and military purposes” was “too little, about the right amount, or too much,” a plurality of 37 percent picked “too much.” Only 28 percent said “too little”–but again, you’re never going to see the New York Times declare a candidate to be “unelectable” for proposing to raise the Pentagon’s budget.

As long as the commercial news media keeps focusing on money instead of a candidate's ideas, the claim of "inelectability" will become a self-fulfilling prophecy. The failure to cover a candidates ideas, exploring them seriously, and instead trying to harpoon a candidacy based on how much money they've accrued is journalistic malpractice at the best. I am convinced it is FAR WORSE than that, however, and it is strong evidence that the media is taking sides based on where rich people are putting their money.
