Historically, gubernatorial elections have tended to be up for grabs between the parties. Statewide electorates are sufficiently eclectic to encourage candidates in both parties to run toward the center, expanding their bases. But the pattern of results is changing, and for an unexpected reason.
For obscure reasons, 36 states hold their gubernatorial contests during midterm cycles. This hasn’t seemed to matter much in the past. But in recent elections, the types of voters who cast ballots in midterm elections has diverged significantly from those that do in presidential cycles. Midterm electorates tend to be smaller, whiter, older and more Republican; presidential electorates tend to be larger, more demographically diverse, and more Democratic.
This pattern helped Republican gubernatorial candidates in 2010.
. . . the GOP is having an increasingly difficult time winning mayoral races in big cities. Of the nation’s most populous cities, only a few have Republican mayors. They include three city-county hybrids where suburban voters can play an outsized role (Indianapolis, Jacksonville, Fla.; and Miami), and a few Sun Belt cities (Albuquerque, N.M.; Fort Worth, Texas; Oklahoma City and San Diego). Gone, apparently, are the days when a Republican like Rudy Giuliani could be the mayor of New York or Richard Riordan could be the mayor of Los Angeles.
Here, as with the U.S. House, geography is destiny. Cities have been magnets for younger, more diverse populations that tend to be socially liberal. This makes the Republican Party, with its national image of social conservatism, a tough sell. Indeed, such mayors as Bill DeBlasio of New York, Ed Murray of Seattle and Bill Peduto of Pittsburgh have been pursuing agendas that are unapologetically progressive.
