Democrat Davis to announce gubernatorial bid

CHRIS TOMLINSON, Associated Press   AUSTIN, Texas (AP) — Fort Worth state Sen. Wendy Davis is expected to formally announce her campaign for governor, becoming the first Democrat to make an official bid for statewide office.   Her campaign was setting the stage Thursday at the civic center where she received her high school diploma in Haltom City. Davis says that her experience going from a single, teen mother to a successful, Harvard Law School attorney informs her politics and her commitment to middle class Texans.   The launch Thursday afternoon will start a long campaign to break an 18-year losing streak for Democrats seeking statewide office in Texas. Attorney General Greg Abbott is the front-runner for the Republican nomination to replace retiring Gov. Rick Perry. Abbott has already raised $25 million, while Davis has a little over $1 million.
