"______ of rivals."
That's right, it's over. Done. All of it. "Team of rivals," "cabinet of rivals," all of it. Over.
The mind-blowingly unimaginative news media has drained that construction of all of its usefulness and left only meaningless catchphrase useful only for identifying those that use it as superhacks.
The concept of staffing a cabinet with former adversaries is as good or bad an idea as it ever was. Nobody has done anything to the thing the now-dead phrase describes. But the phrase itself has been rendered lifeless by herd animal talking heads mouthing it somewhere around infinity times in the last two weeks.
Doris Kearns Goodwin should sue.
