Mr. Hogan appears ready to make similar compromises on his budget and on education funding. It might be too early to characterize him as a pragmatist — after just two months in office, Robert L. Ehrlich Jr., the last Republican in the job, still seemed pretty reasonable, too — but it's clear he's not the extremist-in-centrist-clothing that some tried to paint him prior to election day. We wouldn't want to get too carried away with exaltations quite yet, of course. The new phosphorus rules still amount to a compromise of a compromise of a compromise, and not necessarily "one of the most important steps forward in environmental policy in the last decade," as a Hogan spokesman claims — at least not when 2022 is such a long way off. Rather, it's a modest victory for the cause of cleaning up the Chesapeake Bay, for Mr. Hogan and for lawmakers, as well as a lesson in how a politically divided government in Annapolis can still function properly.
