The overwhelming majority of Atlas forumers predicted Clinton victory.
Now we know that Trump won with 35% margin getting 304 electoral votes vs. Clinton's 227.
To summarize, the best forecast was made by egalitt who on May 4 predicted Trump's victory with double digit margin, and on October 8 wrote: "Trump will not drop. He will rise after defeating Clinton in the second debate. Clinton will trail by 30% on November 8."
The worst result was shown by skoods, who on October 6 stated that "Clinton will win with around 355 electoral votes" thus making a 67.76 + 35= 102.76% error.
Interestingly, egalitt was banned from the forum right after making his prediction.
