What predicts the county vote? · 2012

A map shows where; a regression shows how much. The Democratic margin is modelled on five county traits at once, each standardized — a coefficient reads as “points of margin per one standard deviation, holding the other four fixed.” Pick a trait to follow through all three views:

Across all counties, nationally
dot = effect on the Democratic margin per +1 SD · whisker = 95% CI · all five entered together
…and within each state, separately

each dot = a state (≥15 counties) · filled = significant (|t|≥2) · ┊ national · ← Rep · Dem →

Who Voted for Whom

The American electorate by income, education, faith and more

How each slice of the electorate split between the parties — by their own account. Weighted ANES self-reports from a national sample: they tilt slightly toward the winner and carry no county detail.
