As we watch the elections returns next Tuesday night, the most volatile results may come from governor's races, with perhaps a dozen or more seats changing party hands. That will then set off one of the myths in American politics: that control of the state house affects the presidential race.
Who wins the governorship matters a lot to citizens of Florida or Wisconsin and elsewhere, affecting important issues such as taxes and Medicaid expansion. The affect on the 2016 presidential race, however, will be minimal. A case in point: In 2012, five of the most competitive battleground states were Ohio, Florida, Virgina, Wisconsin and Iowa. All had Republican governors; all five voted for Barack Obama.
