That was created with Adobe Acrobat Distiller -- That font isn't CMR, it's New Century Schoolbook (The Supreme Court likes that font as well). There's also a "gpospec5" font (perhaps GPO is the Government Printing/Publishing Office). I could only find a handful of references the the gpospec5 font, including this one [1] on the previous healthcare bill. Windows user ERN was involved with both, so I would guess he's a GPO employee.
