The state of Texas has numerous types of voting information, including sample ballots and lists of candidates, available at VoteTexas.gov, for state-wide issues. The League of Women Voters website has voter guides based upon location, which includes Texas locations.
Local voter guides can be found on other websites, such as the Dallas Morning News website, which has a guide for each of 12 Dallas districts. Additionally, each party's website has a link from the Secretary of State's website. Voters can find full lists of each party's candidates on the respective websites. Most voter guides list the candidates or issues for the reader to compare. Another approach is the I Side With website that asks a series of questions on various issues and then tells the user which candidate(s) align most closely with those responses.
