It looks like all the CPA legislators will be returning to Austin for the 2015 legislative session. Reps. John Otto (HD 18-Dayton), Charles Perry (HD 83-Lubbock) and Angie Chen Button (HD 112-Garland) all had Republican Primary opponents who they defeated and they face no Democratic opposition in the November general election. Rep. Scott Sanford (HD 70-McKinney) had no primary opposition and has no general election opponent. While Reps. Phil Stephenson (HD85-Wharton) and John Frullo (HD 84-Lubbock) had no Republican Primary opponents, they both face a Democratic challenger in November. Both of their districts appear to be safe Republican districts, so I believe they will be back in Austin too.
CPAs did lose one representative that is a member of the CPA family. Rep. Linda Harper-Brown (HD 105-Irving), whose husband is a CPA, was defeated in the Republican Primary by former Rep. Rodney Anderson. Anderson was a one-term representative who was paired with another incumbent in the redistricting process and did not run for re-election. He decided to try again in HD 105. To some degree Harper-Brown is a victim of that same redistricting. Her new district overlapped much of Anderson's former territory.
The other CPA family member, Rep. Geanie Morrison (HD 30-Victoria), whose husband is also a CPA had no primary nor general election opponent, so she will be back in Austin in 2015.
