Earlier this year, Roll Call — the news source dedicated to covering Capitol Hill — ran a short headline that summed up much of U.S. policymaking today. "It’s the states, stupid,” the magazine declared. Gridlock continues to reign in the nation’s capital, with power divided among two political parties that have become more ideologically distinct and among members of U.S. Congress who have become more ideologically distant from one another. That contrasts with trends at the state level, where a single party now controls the governor’s office and both legislative chambers in close to 80 percent of state capitols. That is the highest rate of unified government in more than 50 years.
