Abraham Lincoln has been called The Great Centralizer. We've often thought of Barack Obama as The Great Divider. What's happening among the 50 states is a fusion of centralization and division.
In 37 states (including Oklahoma), one political party controls the legislature and the governor's office. That's the highest number in 60 years. Voters are “centralizing” government into the hands of one party or the other rather than dispersing power among the two parties. On the other hand, the trend shows a deep division among the states that's not true even in Washington, where one party controls the White House and the Senate but not the House of Representatives.
The result of one-party control is evident in the flurry of activity to pass items long on the agenda of Oklahoma Republicans — tort reform, workers' compensation reform, income tax cuts, etc. Unfortunately, the state Supreme Court has been striking down such legislation based on the constitutional prohibition against logrolling.
In Colorado, Democrats now control state government. The result is evident in a flurry of laws long on the Democratic agenda — gun control, immigration reform, Medicaid expansion, etc.
