Maryland has just come off an extremely consequential eight years under Gov. O'Malley. We have witnessed major policy changes on taxes, spending, the environment, criminal justice, energy, social issues, gambling, education and more. There are plenty of progressive interest groups pushing for the legislature to keep up the trend, the results of the election notwithstanding. And Mr. Hogan is no doubt also feeling pressure from conservative groups to roll back as much of the O'Malley legacy as possible.
