See If You Can Guess How Many People Voted 'For' and 'Against' This Bill
It reminds me of the famous headline, 'Harvard Beats Yale, 29-29.'
From The Hill today:

I'm highlighting cases like as a way of documenting a "change in norms," in real time. (Thanks to reader CS for the tip.) The "rules versus norms" question is increasingly important for understanding what's happening to our system of self-government - including what's happening with the Supreme Court, as I'll get to soon.

Is this a matter of necessary journalistic compression? No. The headline above would have fit just as well if it read "Senate blocks Democrats' measure..." And the crucial explanatory sentence in the second paragraph could just as easily have said "Sixty votes were needed to break a filibuster on the measure."
Press coverage like this, or comments like Antonin Scalia's, obviously did not drive the transformation of Senate norms. But they certainly ratify it. There will come a time when "informed" readers have no idea that the Senate ever was able to pass important measures on "merely" a majority vote. And I'll save for another time the zillionth discourse on why the conversion of the Senate into a minority-veto body is destructive, no matter which party is in control.
Update: The day after the item with its misleading headline went up, it's still there, headline uncorrected.
