It also shows you how skittish the networks have become since 1980 (and definitely since 2000). To call Missouri TCTC in 2016 was ridiculous.
I remember in 1980 how NBC was calling state after state for Reagan once the polls closed, for which they were criticized. And they were right in every instance (even in the Deep South states like Alabama, Mississippi, and South Carolina where Reagan barely won). The only race of significance I think the networks called wrong that year was Mack Mattingly's upset of Herman Talmadge for the GA Senate seat.
The immediate projection of Clinton winning GA & NH in 1992 was so pathetic I wish he would have lost them just to embarrass whoever was making those ridiculous calls.
