LINCOLN PARK, Mich.— Last Thursday night, Rick Santorum’s campaign sent out a routine notice of the candidate’s schedule for the next day. It said that on Friday evening Santorum would “hold a rally in Lincoln Park, Mich.”

Twelve hours later, the campaign sent out another notice, this one under the heading MAJOR ANNOUNCEMENT.  It said that on Friday evening — same time, same location — Santorum would “unveil his agenda for the first 100 Days Economic Freedom Agenda of the Santorum Administration.”  Just like that, an everyday campaign appearance was re-cast as a major policy speech.
