K.C. Dermody has this column at Yahoo News on Republican presidential candidates and history, using terms such as "incredibly misinformed" and "completely dishonest."  Dermody blasts Romney for a comment about the Massachusetts Supreme Judicial Court's decision on same-sex marriage, in which Romney refers to John Adams as the author of the Constitution.  Dermody says Romney needs a history lesson, because Adams was in London when the United States Constitution was being written, as indeed he was.

Just one problem, as James Taranto points out at the WSJ.  Romney wasn't talking about the United States Constitution.  The Mass. SJC decision was an "independent state grounds" case based on the Massachusetts Constitution.  Guess who is the principal author of that document.
