There were no “shenanigans” at least not in the normally understood full context of that word.
The notion that the networks did this to favor Donald Trump is laughably insane.
One could ask why they did it—only they know.
But it is the full context that makes the claim absurd—the nature of caucuses and caucus goers, the Iowa weather, the nature of the blowout, the mass media proven hatred for Trump.
The big networks definitely want Trump to win the nomination, he’s their number one cash cow. To call me insane when you are ignorant of this obvious fact is hysterical.
