Margin is the Democrat's share minus the Republican's, in percentage points; Nation is the same for the national popular vote. "Other" is everyone else combined, or the leading third-party candidate where one took 5% or more. Vote counts from 1976. Turnout is ballots cast as a share of eligible voters, from 1980 (UF Election Lab; the newest year is preliminary).
