The Republican Party of Texas has issued an advisory to party members cautioning that it may not be possible to have an unified April 3 - or even April 17 primary.
[T]he schedule put forth by the court today does not lend itself to an April 3rd unified primary date. While it is still theoretically possible to have an April 17th primary date (if the court issues a very quick decision after the February 15th hearing and immediately drew new maps), in all likelihood, this new schedule means that a new single unified primary date could not be held until at least April 24th.
It remains the Republican Party of Texas’ position that in order to comply with the process specified by the Texas Election Code for the selection of delegates to the State Convention, that a primary must be held on or before April 17th. Consequently, the State Chairman, in consultation with party leadership, is examining all options in order to resolve this conflict and will issue further advisories once a recommended course of action is determined.
