I feel it. Do you? Finally, after decades of undeserved dominance, Fox News as we’ve known it is vulnerable. Why? Because the dramatic divergence between the channel’s coverage and the reality out here in the world is seeping through to the Fox audience. I don’t expect the death tomorrow or next month or this year of what Ailes wrought. But I do expect the outlet to fall gradually into shadow unless it morphs, relegated to niche status as a hangout for the folks who don’t want to know what’s out there beyond their fear and suspicion and resentment.
