Republican leaders say the only “responsible” way to name a replacement for late Comptroller Judy Baar Topinka is through an appointment by Republican Governor-elect Bruce Rauner.  Senate Republican Leader Christine Radogno and House Republican Leader Jim Durkin released a joint statement Thursday stressing provisions in the Illinois Constitution.  Earlier in the day, Governor Pat Quinn announced he’s calling lawmakers to Springfield next month to consider a 2016 special election for comptroller.  Topinka died last week.  She had won a second term in November.  Quinn says voters should have a say.  However, Republicans including Rauner say a rushed decision for a special election would certainly face costly legal challenges.  In a statement, a Rauner spokesman says any changes should apply to future vacancies so they don’t look “overtly political.”
