The headline change occurred at some point between 1:41AM on 2/11, when I posted the original
article, and 6:23AM on 2/11, when I
noted it on the original thread.
It's not the only headline about the O'Malley/NCPAC issue that changed. The headline of Michael Olesker's Baltimore Sun column did as well. The Baltimore Sun also later cleared up what was likely a factual error - Olesker at first implied that MD4Bush is the Washington Post. That Free Republic thread is
here.
