There is an outside chance that Mrs. Clinton can pick up as many as 249 EVs east of the Mississippi, meaning that Colorado, New Mexico and Minnesota would make it a lock.
However, I don't expect that to happen, for several reasons. The most important reason is that television news is a circus industry now, beholden to ad revenue. I would not be surprised to learn after the fact that CNN agreed to keep the issue in doubt until after 9pm western in order to charge a higher ad rate in California.
Another reason is that Donald Trump is setting himself up to be the news networks' direct competitor, and he will be praying for a 2000-level fuck-up that he can use as his casus belli against the news networks. So they're going to take their time making projections--and projecting the enormity of Trump's defeat.
Still another reason is that, thanks to the fact that we have a naked micropenis Fascist in the race who has repeatedly alleged that the race is stacked against him, who has enlisted the help of unfriendly foreign governments, and who encourages a win-or-fight attitude among his hopelessly ignorant supporters, this election is even more of a national security issue than it normally is. It needs to be made clear that Trumpkins are a small and incompetent minority of voters, lest we face another 1860-type crisis.
