The Cuomo case also shows the benefit of the governor, rather than gay rights activists, taking the lead. Mr. O'Malley said he made phone calls at advocates' direction this year to try to sway a dozen or so wavering votes. That's similar to the role Mr. Cuomo, then New York's attorney general, played in a previous, failed attempt to legalize gay marriage. This time around, he took charge and produced a more forceful, organized and strategic lobbying effort. There is no reason to believe the same wouldn't be true in Maryland. Governor O'Malley's chief legislative aide, Joseph C. Bryce, is the best in the business. With all due respect to Equality Maryland and the other advocacy groups that worked on this issue, the governor is delusional if he thinks they know better how to round up votes in Annapolis than Mr. Bryce does.
