The same dynamic has played out on the state level. Republican governors in Ohio and Georgia have campaigned on criminal justice reform. In Maryland, Republican former Gov. Robert L. Ehrlich Jr. was much more open to clemency and commutation requests than the Democrats who preceded or followed him in office, and he is still speaking out on the issue, largely to conservative audiences. Maryland's new Republican governor, Larry Hogan, has indicated a desire to follow Mr. Ehrlich's lead, and his administration has already identified a dozen people who have served significant sentences who could be candidates for commutations or parole, along with nearly 300 who could be pardoned to erase relatively minor crimes from their records. All those cases will require more review and a final decision by the governor, but it's safe to say Mr. Hogan is proceeding much more quickly than Democratic former Gov. Martin O'Malley, who didn't approve his first commutation until he had been in office for more than five years.
