Support for embargo keeps shrinking

After Richard Lugar went public with the argument that the Cuba embargo "has failed to achieve its stated purpose of 'bringing democracy to the Cuban people,'" we are coming to a pretty remarkable state of affairs in which it is getting harder and harder to find supporters of current policy outside Florida.

The Republican Party has almost entirely deserted it. Governors, business leaders, and pundits alike are finally coming to the same conclusion. It has not normally been a policy where you would expect to find bipartisan agreement. And yet here we are.

Tom Shannon is already leading a review of U.S.-Cuba policy, which will obviously provide strong clues about what the policy change will look like. Something is going to change, but it's hard to tell how radical it will be.
