the texas democratic party holds three tiers of caucus events to select its delegates: precinct conventions, county and senatorial district conventions, and a state convention. the precinct conventions immediately followed the primary, a process in 2008 that was advertised as the "texas two-step". senator royce west is chair of the advisory committee on the texas democratic party convention/caucus system, which is charged with investigating the caucus system, including whether to retain the texas two step. former texas attorney general jim mattox testified against the texas two-step at a hearing of senator west's committee held in austin.
