There may be good reasons for why this is taking so long. The Capitol is a busy place, and the elected officials charged with making these appointments have had plenty of other things to deal with during the legislative session. At the same time, finding citizens who are capable and also willing to give their time could be a challenge.
But voters endorsed the state question with the expectation that changes would soon follow. The remaining vacancies need to be filled so these panels can get on with the important work at hand.
