Why did the president cite 84,000 for job growth?

In a speech in Youngstown, Ohio, last Friday, President Obama said, “[O]ur businesses created 84,000 new jobs last month.” That was different from the official Labor Department numbers released that morning, which put the number of new jobs at 80,000. Obama was pointing to private-sector job growth. Government payrolls actually fell by 4,000. Obama has blamed the weak economy on GOP reluctance to help local and state governments maintain their payrolls.
