In recent years, Republicans have come to dominate most of the state legislatures in the US. Ironically, it was during the Obama-era that the GOP made major headway in states that had long been considered safely blue. State legislatures are now redder than they've been in nearly a century, and in most parts of the country, one party holds all the levers of power (governorship and legislatures). For the first time since 1914, there's only one split legislature in the entire country: Minnesota. To be sure, some state races are bucking the trend: Kentucky and Louisiana, both deep-red states, recently elected Democratic governors. Here's a look at how Democratic and Republican control of state legislatures has evolved over the past four decades.
