Wikipedia’s article on the National Popular Vote Plan can be seen here. It has a chart that shows the progress of the bills in each house of the legislature, which is more comprehensive than National Popular Vote Plan’s own site. However, as of April 3, the Wikipedia chart does not yet reflect that bill’s passage in Maryland.
The Wikipedia article currently reflects the passage of the bill through both houses of the Maryland legislature, and has reflected this fact since the afternoon of April 2:

It’d also be remiss to fail to credit one Wikipedian, http://en.wikipedia.org/wiki/User:Nightstallion , for doing the lion’s share of the work maintaining and updating Wikipedia’s article on the National Popular Vote Interstate Compact. Kudos!
