The Associated Press reports Davis, who is scheduled to announce her political plans Oct. 3, will jump into the race to succeed Republican Gov. Rick Perry. The AP story is based on two unnamed Democrats with knowledge of her decision.
Davis has become a Democratic Party sensation across the country for her marathon filibuster in June against a bill to restrict abortion. Though the Fort Worth lawmaker temporarily succeeded in blocking the bill, the measure eventually passed the Legislature and was signed into law by Perry.
Despite her near-celebrity status among Democrats, Davis would have an uphill fight in a campaign for governor. No Democrat has won a statewide Texas office since 1994.
