I speculated why journalists would do such a thing, but didn't have space for an exhaustive list.

But it's clear that one of the things journalists aim to do is retain their once-vaunted position as gatekeepers, as the idea-people and fact-dispersers who define the terms of allowable debate.

By ignoring the competition, they narrow the terms of this year's presidential campaign, allowing their inexplicable favorite, Hillary Clinton, an advantage going to the polls.

But poll taking and reporting is not the half of it. Tim Graham, writing at Newsbusters, notes how the Gray Lady rigs the intellectual field. "The New York Times appears to be playing games again with conservative authors, trying to keep them off its vaunted (and secretively manipulated) Best Sellers list. This has happened to Ted Cruz, to Dinesh D'Souza, and to David Limbaugh."
