State Sen. Wendy Davis, standing on the stage where she got her high school diploma more than 30 years ago, finally announced Thursday what has been anticipated, telegraphed and talked about for weeks: She is running for Texas governor. Davis promised to be an advocate for those who feel they no longer have a voice in the halls of the Texas Capitol, to fight for more education dollars and to take on Republicans leaders who she said are listening to their campaign contributors instead of average Texans. "In Austin today, our current leadership thinks promises are just something you make to the people who write big checks," she said. "But the promise I’m talking about is bigger than that. It’s the promise of a better tomorrow for everyone. Texas deserves a leader who will protect this promise. Texas deserves a leader who will keep it."
