The September 6 issue of the Washington Post has this editorial, criticizing Maryland’s hyper-technical rule for determining whether signatures on petitions are invalid.  The constitutionality of the rules has been in both federal court and state court since last year.  The federal case is pending in the 4th circuit and is Kendall v Howard County, 09-2304.  The state court case is Norman v Howard County.  Thanks to ElectionLawBlog for the link.
