INDIANAPOLIS (AP) _ House Speaker Brian Bosma is readying a drive to write Indiana’s ban on gay marriage into the state constitution. 
 
  Bosma says the pair of rulings the U.S. Supreme Court handed down on gay marriage Wednesday cleared the way for state action on the issue. Bosma and Senate President Pro Tem David Long held off pushing the issue earlier this year while awaiting the high court rulings. 
 
  Gay marriage is already banned in Indiana, but lawmakers and marriage activists say the state law could be overturned in a state court unless it is written into Indiana’s constitution. Amending the constitution requires lawmakers to approve a measure in two consecutive sessions and then place the issue before voters.
 
  The measure has already passed once.
