Flores made an unsuccessful run for City Council in 1997, had served as a Democratic precinct chairwoman, and attended numerous demonstrations.
In Houston's last mayoral election, Flores was in the news for arranging to enter a second man named Bill White in the race. The Bill White who later won the election learned of the plan, talked Flores out of following through with it, and paid her $5,000 from his campaign funds.
Dennis Keim said he met Flores in 1992, and the two became close friends and often were allies despite being members of opposing political parties. He said he helped to keep her computer running so she could update her Web page, www.housnitch.com.
"When it came to government spending, she was the watchdog," Keim said. "One little renegade lady who was taking on the City of Houston."
He said she had "a network of people who fed her information," and her "biggest, latest fight" has been trying to get the city to pass an ordinance to protect whistle-blowers.
