Given that it was his single state of the '84 election and given how tight it was (4K votes), I really wonder. There was a youtube up with some brief NBC coverage. When Brokaw announced that they were projecting MN for the Democrat, you could see his smile of Glee and there were claps and cheers audible in the background.
If I'm not mistaken, ABC actually called the state soon after 9pm when the polls closed, but for CBS and NBC, it was the final state called that night.
Because he was happy about winning his home state?
