[FRIAM] high turnout and tight races?

Thu Oct 29 11:38:30 EDT 2020

For an ordinary sum of values, as described by the central limit theorem with finite variance, variance increases linearly with N.

It is relative variance — variance normalized by the square of the mean — that decreases with N as 1/N.

Young people are voting in unprecedented numbers and are reportedly voting against Trump.  Similarly the elderly, who favored Trump over Clinton by 10+ percentage points in 2016 are favoring Biden over Trump by a similar margin, according to polls.
