Sources close to state Sen. Leticia Van de Putte, D-San Antonio, say she is poised to make an announcement on her political future on Friday. But the likely Democratic contender for lieutenant governor is expected to do what gubernatorial candidate Wendy Davis did: reveal a future date for a formal announcement. The two women are now inextricably linked for their roles in the June 25 filibuster against a law that further regulated abortion facilities. Their appearance at the top of the ticket will likely heighten enthusiasm with the Democratic base.
