INDIANAPOLIS (AP) _ Republican Gov. Mike Pence has told a Statehouse rally that Indiana’s charter school and private school voucher programs are key components to improving the state’s education system.
 
  Pence, Republican legislative leaders and former Indiana Pacers star Jalen Rose spoke Monday to the crowd of a few thousand people, mostly children from charter and private schools around the state.
 
  The Legislature is considering a proposal to expand Indiana’s 2-year-old voucher system that already is the nation’s largest. 
 
  A bill already approved by the Indiana House would allow kindergartners and some other children to be eligible without first spending a year in public schools.
 
  Democratic legislators question that expansion, saying the program hasn’t been in place long enough to gauge its effectiveness.
