INDIANAPOLIS (AP) _ Legislation intended to expand mass transit in central Indiana is drawing opposition from tea party activists who oppose the local tax increases that would fund the proposals.
 
  The bill would authorize Hamilton and Marion counties to hold voter referendums on whether to raise local income taxes to pay for most of the local portion of the proposed $1.3 billion plan to expand bus service and possibly add a commuter rail line.
 
  But Chase Downham, president of the Indiana chapter of Americans for Prosperity, tells The Indianapolis Star the group is concerned not just about the proposed tax increases but “the overall cost of such a proposal.”
 
  Republican state Rep. Jerry Torr of Carmel says he’s not concerned tea party opposition will derail the mass transit bill he’s sponsoring.
