Baker is going to be a bland, competent administrator in the vein of Paul Cellucci.
Larry Hogan, I fear, will attempt to Brownback Kansas ("If we just decimate the tax base, we'll create millions of jobs! Because Laffer Curve!") and possibly get mixed up in some nasty social issues-related legislation. Massachusetts Republicans are sane. Maryland Republicans at this point are basically a kooky, Southern-tinged bunch.
Larry Hogan made it out from a long time ago that he would not touch social issues, agreed with gay marriage and after being elected actually said he would not push to repeal the gun control laws
that many in the Appalachia and Chesapeake rural sections of the state gave him huge margins in hope he would repeal. Which caused a lot of upset.
The real coming fight between him and the democrat controlled state legislature is over spending+taxation. One of his main election points was that he would push to repeal the rain tax and promised to veto budgets as long as the legislative democrats did not agree to cut taxes and spending.
