On August 26, the Texas House passed SB 13, which authorizes a later 2022 primary. The bill does not set the date; instead it sets out a formula, keying the date of the primary to the date when redistricting is finished. The vote in the House was 91-25.
The Texas primary date has big implications for ballot access, because petitions for a new party or an independent candidate can’t circulate until after the primary. So if the primary is later, the period for petitioning shrinks. Either that problem will be eased by the legislature, or a court is likely to do so. A ballot access case is already pending against the existing law, Miller v Hughs, w.d., 1:19cv-700. Discovery is almost completed.
