But when it comes to politics, it doesn’t matter; whichever way the rot runs, watching Fox now is like getting a peek into Trump’s war room and, in a larger sense, into the future of the right in America, however ugly that picture may be.

Now there is an extra layer of intrigue. Suddenly Fox News feels like a nation up for grabs, and there is growing, palpable drama on its sets.

The network’s daytime anchors — people like Shep Smith and Chris Wallace, who fall on the news reporting side of Fox’s opinion-reporting divide — have always grumbled about the network’s nighttime pundits, talkers like Tucker Carlson, Sean Hannity and Laura Ingraham. Now the two sides are at open war, sniping at each other daily over the seriousness of impeachment and the very legitimacy of any inquiry of the president.

On impeachment, Fox News’s news side has been excellent. There were many moments in the last week where I felt shocked and gratified by the seriousness with which Fox was taking impeachment.
