With its swanky private country clubs, large estates and high per-capita income, Douglas County just south of the Denver metro area is a major Republican stronghold in Colorado. The county, which has the state's highest average median household income at $82,929, has only gone for a Democratic presidential candidate three times since 1920 — twice for FDR in the 1930s and 40s, and once for Lyndon Johnson in 1964.
