She was the frontrunner to replace Ronnie Earle, and she did. From the Texas Observer in 2008:
Each of the four candidates to replace Earle has a different view on the role of the integrity unit. The early front-runner is Rosemary Lehmberg. She has worked in the Travis County DA’s office for three decades (preceding even Earle’s arrival by six months). For the past 10 years, she’s served as first assistant district attorney-Earle’s second in command. He gave her his enthusiastic endorsement after the filing deadline in early January. A stately woman of 58, Lehmberg is the most experienced candidate. She has worked in and supervised every division of the DA’s office, including the integrity unit. “She has the most experience. She has the best judgment that has been tempered by steel,” Earle told reporters. “So I think she would make the best district attorney for Travis County.”
Lehmberg characterized the integrity unit as one of the office’s most important divisions. “I feel very strongly that our government is not for sale, that our democracy is not for sale,” she said. “I have always viewed our role as somewhat the guardian over the state Capitol. And that doesn’t mean you’re heavy-handed, that doesn’t mean you overreach. But that separation, that balance, that mutual oversight is healthy and necessary.”
She argued that such power must be used delicately. She noted that the office receives numerous complaints of corruption-many of them politically motivated-that must be weeded carefully. “In the political world, the mere fact of an investigation can destroy a career. We try to thoroughly ferret out the facts and the law before [a case] goes too far and it winds up on the front page of the paper,” she said. “That doesn’t mean we hide it, but I have learned how sensitive they can be.”
Replacing Ronnie Earle - The Texas Observer
I ordinarily wouldn't make a comment on a politician's looks, but the article refers to Lehmberg as "stately." This is a most generous word. She looks like a man wearing makeup. I am not kidding. Maybe the writer meant her hair?
