*NOTE: As of 3 July 2019, the page is titled Republican or Democratic Party Nominees. However, with the enactment of House Bill 2504, the provisions also apply to parties that nominate by convention, such as the Green and Libertarian Parties.

The presentation below from October 2017 features longtime GPTX activists katija gruene and Laura Palmer. It specifically addresses petitioning for ballot access for the Green Party in 2018. As of June 2019, thanks to HB 2504, the Green Party no longer needs to petition for a ballot line unless and until none of its nominees receive 5% of the vote in a statewide general election for ten years.

However, much of the presentation remains useful and relevant. It does contain some helpful, practical pointers on the logistics of collecting signatures, applicable to individual candidates petitioning to run for office. For example: Carry multiple legal-size clipboards—or better yet, multiple custom-cut cardboard rectangles, with the petition forms rubber-banded to them.
