Woo-hoo! Rhode Island, Delaware, now Minnesota! 12 states plus DC and 3 tribes.
I'd somehow not noticed Maryland approving it in 2012 -- by popular vote, as in Maine and Washington.
Illinois will be next if the bill can escape the House; Senate has passed it and governor has said he'll sign. (Also, Michael Madigan is still Speaker? Wow.)

New England + NY is a bloc, Maryland and Delaware are a tiny bloc which will be hooked up to NE if New Jersey can override Christie's veto, or gets a better governor, and Minnesota and Illinois would make a bloc with Iowa.
