This article analyzes the views of three different Iranian opinion groups - Conservatives, Moderates and Reformers - based on their responses to several measures of "regime support" contained in WPO's September 2009 survey. The three groups were initially identified on WPO's February 2008 Iran survey using Latent Class Analysis that was presented in an earlier article, "Iranian Public is Not Monolithic ...". The same three groups were recreated on WPO's September 2009 Iran survey, as well as its earlier 2008 survey, using an easily replicable 7-point scale applied to responses on the same three government support measures. All three of the these measures tap the theoretical construct of "regime support," with Conservatives consistently supportive of the regime, Reformers consistently opposed, and Moderates having mixed views.
