They put a special arrow with a "Madison, WI" label on the "Daily Show" map:
Here's the whole article, "‘Duck Dynasty’ vs. ‘Modern Family’/50 Maps of the U.S. Cultural Divide/Americans have been clustering themselves into cultural bubbles just as they have clustered in political bubbles. Their TV preferences confirm that."
The dot that is Madison, Wisconsin shows up in all the maps, but somehow it's the "Daily Show" one that made the NYT feel a special need to point at us.
I think the NYT is looking for ways to serve readers who are agonizing in the aftermath of the election, and pop-culture-focused political articles may seem helpful in moving them through the stages of grief.
