From a Times/Texas Tribune article about a Texas state senator: "Ms. Campbell, a physician certified in emergency medicine and ophthalmology, was elected in 2012 after ousting a 20-year incumbent, Jeff Wentworth, in a Republican primary runoff in Senate District 25, which stretches from northeast San Antonio to South Austin and includes parts of six counties."
If she's a physician, why doesn't the Times call her "Dr. Campbell" instead of Ms. Campbell, which is what it calls her throughout the article? The "Dr." is what Times style usually dictates for medical doctors.
