• 2012: Utah, Nebraska, Kansas
• 2008: Alaska, Louisiana
• 2004: Texas
• 2000: Montana
• 1996: Mississippi, Indiana, South Carolina
• 1988: New Hampshire, Florida, Arizona, Nevada
• 1976: Colorado, Vermont
• 1972: Georgia, North Carolina (only occurrence)

Longest current streak in R Top 10:

• Idaho (since 1972 when 11th in huge landslide; otherwise since 1960)
• Oklahoma, Wyoming (since 1992)
• Utah was most Republican every election 1976 to 2004 and would qualify but for strong third party in 2016

It’s extremely plausible Missouri will soon become a regular in Republican Top 10s.
