Does sprawl help Republicans or Democrats or neither?
THE SUBURBAN MYTH
By Michael Lewyn
In 2004, as in past elections, Republicans lost central cities overwhelmingly, did better in inner suburbs, and did better still in low-density outer suburbs (also known as "exurbs."). It could therefore be argued that the correlation between suburbia and conservatism indicate a causal relationship between the two - that is, that the lower densities and automobile dependence of suburbia somehow turns Democrats into Republicans, or that the high population density and other features of urban life turn Republicans into Democrats.
If either proposition was true, we would find that central city Republican strength held steady in declining cities, because urban life inevitably creates Democrats - or that central city Republican strength even increased, as declining urban densities turned urban Democrats into Republicans.
To test this theory, I compared 2004 election returns in seven population-losing cities with 1960 election returns. Why 1960? First, because 1960, like 2004, was a very close election. Republican presidential candidates received just under half of the popular vote in 1960 (49.5% to be exact), and just over half in 2004 (50.7%). Second, because 1960 was to some extent a pre-sprawl election: most northern cities had just begun to lose population in the 1950s, and were far more populous and affluent than they are today.
In fact, Republican strength in central cities has nosedived in recent decades. In every city, the Republican share of the popular vote decreased by at least 10 percentage points. However, suburban Republican strength did not consistently increase. Republican strength held steady in some suburbs, increased in a few, and nosedived in others.
How come? Suburbanites tend to be married and white- the very groups most likely to be Republicans. Thus, the movement of married whites to suburbs has been disproportionately a movement of Republicans, which in turn has demolished the GOP's urban base. By contrast, the remaining urbanites tend to be either young, single whites, Hispanics and African-Americans: three groups that disproportionately tend to vote Democratic. The same is true in some inner ring suburbs, thus reducing GOP strength in those suburbs: for example, the Republican vote share in suburban Cook County (Chicago's inner ring suburbs) nosedived from 59% in 1960 to 40% in 2004.
Although married whites are more Republican than urban singles and minorities, they may not be any more Republican than voters already living in rural and suburban counties. Thus, the movement of married whites to outer suburbs has not consistently increased Republican support in outer suburbs. In other words, if migrants to growing Exurban County X are 55% Republican, and County X's existing residents are 60% Republican, County X actually becomes less Republican even as its political influence increases. So fast-growing exurbs such as McHenry Chicago near Chicago and Chester County near Philadelphia are either less Republican than in 1960 when they were rural counties, or are only slightly more so.
Thus, urban decay and suburban growth are, for all practical purposes, a kind of Democratic gerrymander: Republican voters are packed into already Republican rural areas-turned-suburbs, while the city and inner suburbs become Democratic areas. Thus, sprawl actually may increase the number of Democratic mayors and other local officials by increasing the number of heavily Democratic municipalities.
