BS! At 8pm, folks in the Central, Mountain and Pacific time zones will still be voting. And that doesn't include Alaska and Hawaii.
Assuming, of course, you mean 8pm Eastern Time.
NBC News projected Reagan as the winner at 8:15 pm EST (5:15 PST), before voting was finished in the West, based on exit polls. (It was the first time a broadcast network used exit polling to project a winner, and took the other broadcast networks by surprise.) Carter conceded defeat at 9:50 pm EST.

It has to be 8PM PST.
Networks dont call elections before the polls close, and are cagey about making mistakes.
They wont call it for Romney early. But that’s okay ... SO LONG AS OBAMA IS FIRED.
