The Fall of the Texas Republican Party?

This Texas Monthly article called Primary Lessons talks about how, especially among the Republican party, there is no discussion on advancing the state.  It says that the Republican party has splintered and the primaries are causing a civil war between the two factions.  According to the article, Abbott has chosen to run far to the right side of the political spectrum, keeping a similar political agenda as Perry has had for the last 14 years. “The concern for Abbott ought to be that the state party is verging on intellectual bankruptcy, desirous only of turning on those politicians who might actually want to do something.”  I foresee a fall of the Texas Republican party because we have had 14 years of the Rick Perry administration and none of the current Republican candidates seem to want to do anything different.  I do not see them developing plans to change things that are social concerns, like school systems, public infrastructure, and public welfare.
