Barack Obama Elected President: "the data show a consistent positive trend that continues through the declaration at 23:00 ET and his subsequent speech to 125,000 people at Grant Park in Chicago and the public via TV. The formal data segment overall shows a modest positive trend through the 24 hour period. Chisquare is 86806.274 on 86400 df, for p = 0.164 and Z = 0.977. This represents a relatively large effect size compared with the average of Z = 0.33 over the full GCP database."
"remembering that we cannot reliably interpret single events like this, nevertheless it appears that the election shows at least as strong an effect as the terror attacks"
