Her roots in the state, as she never fails to remind voters, reach far back. One of her national co-chairs, Raul Yzaguirre, remembers meeting Clinton in 1972, when she went to south Texas to register Hispanic voters for George McGovern. "It was a bit of a culture clash," he says, recalling the blond, bespectacled young woman who asked him how to make tamales. When her husband was president, she visited repeatedly, and over the years she's become steeped in Tejano culture.
The border area holds the most promise for her, with its rich reservoir of Latino voters—a group that's been a base of support. Hidalgo County, home to McAllen, is 90 percent Mexican-American and a place where the old-timers used to place two photos on the mantel: one of the pope and one of JFK. "We're the bluest part of a Red State," says Jerry Polinard of the University of Texas-Pan American. "When we talk about building a fence down here, we talk about building one on the north to keep the Republicans out." But under the state's inscrutable delegate-allocation system, this heavily Hispanic area will have comparatively fewer delegates to award. So Clinton will have to compete for voters all over: liberals in Austin, old-line Democrats in the middle, blacks in Houston and Dallas, and rural traditionalists east and west.
