Oklahoma primary and runoff historical analysis

David Beaudoin of the Local and Special Elections blog has analyzed Oklahoma runoff election results beginning with the 2008 election cycle and has made some interesting findings that set Oklahoma apart.

Among other findings, Beaudoin notes that, unlike other states, Oklahoma incumbents rarely find themselves in runoffs -- none this year, and only one since 2008. Conventional wisdom says that if the first place finisher had 40% or better in the primary, he's a shoo-in for the runoff, but Beaudoin finds that this isn't the case in Oklahoma.

Beaudoin, a CPA and financial analyst, backs up his psephological analysis with a chart (linked from his analysis) showing all runoffs in Oklahoma State Election Board records since 2008 (statewide, federal, and legislative races) alongside the primary results for the same races.

Oklahoma's relative turnout rate -- comparing runoff turnout to primary turnout is comparable to that of other runoff states.
