SAN ANGELO, Texas – The mayor of this West Texas sheep ranching town offered a stunning explanation when he suddenly resigned: He was in love with a man who was an illegal immigrant and had gone to Mexico.

They had to move, he said, because there was no legal way for them to remain together in the United States.

"It wasn't a decision that any U.S. citizen should have to make," former Mayor J.W. Lown said in an interview from Mexico. "I left a home. I left a ranch. I left a promising political career."

During his tenure, Lown transformed the $600-a-year, part-time job from a mostly ceremonial position to a hands-on office. He actively appeared at thousands of community functions and went to Washington to lobby for the West Texas town — spending his own money after a few residents complained about taxpayers footing the bill.
