Lytle is a blink-and-you'll-miss-it kind of town, one of hundreds that dot the vast flat ranchlands of southern Texas. A smear of houses by the main highway between San Antonio and Laredo. Population: 2,383. The first streets only got paved here in the years after the second world war. A sewage system took a little longer, not being built until the 1960s. In short, Lytle, Texas, has never been big enough to have much impact on the politics of the Lone Star state. And few Texas politicians have ever paid much attention to it.
