All of us with nothing at stake always seem inclined to think Maritime Union would be a good thing. Most acknowledge it is highly unlikely to happen. Fun to see it back on the agenda, however.
Historical analogies? Actually, maritime union was not a serious proposition in 1864 either. None of the Maritime legislatures were at all serious about it when they sent delegates to the conference in Charlottetown.
What to call the new province? The National Post suggests "Nova Brunsward," which is another reason it ain't going to go anywhere. But obviously the name should be The United Provinces of Nova Scotia, New Brunswick, and Prince Edward Island. The three places really exist, and merging their governments would not change that, so why try to erase their names? The U.P. -- I could go for that.
