HALTOM CITY, Texas (AP) -- Democrat Wendy Davis has declared her candidacy for governor of Texas.
In an email to supporters, the Texas state senator promised Thursday to represent the interests of middle-class residents, focusing on education, economic development and health care. She was expected to make a formal announcement later in the day at a rally in Haltom City.
The Fort Worth lawmaker came to national attention in June for her nearly 13-hour filibuster that helped temporarily block new statewide abortion restrictions. The law later passed.
Since her filibuster, Democratic activists have called on Davis to break a 20-year losing streak for Texas governor.
Attorney General Greg Abbott is the front-runner for the Republican nomination. He's raised $25 million.
Davis has a little over $1 million.
Republican Gov. Rick Perry has chosen not to seek re-election.
