DALLAS (AP) — H. Ross Perot, the colorful, self-made Texas billionaire who rose from a childhood of Depression-era poverty and twice ran for president as a third-party candidate, has died. He was 89. The cause of death was leukemia, a family spokesman said. Perot’s 1992 independent run for the White House drew 19% of the vote, among the highest totals ever for a third-party candidate. It featured folksy sayings, including one that became a national catchphrase: “It’s just that simple.”
