Voters have a chance to cast ballots early for the Nov. 5 election involving nine proposed amendments to the Texas Constitution.
Early voting opened Monday and runs through Nov. 1. One proposal would use $2 billion from the state's Rainy Day fund to finance major water infrastructure projects.
Secretary of State John Steen says Texans can cast ballots at any early voting location in the same county as their registration.
It's also the first statewide election with photo identification requirements for in-person voting, with seven forms of ID accepted.
Common forms include a Texas driver's license, a U.S. military identification card or a passport.
Voters in state House District 50 will choose a replacement for Democrat Mark Strama of Austin, who resigned in July to join Google Inc.
