Throughout history, "full employment" is considered to be an unemployment rate between 4-5%. That's because at least 4% of the population simply will not, or cannot, work. In fact, the unemployment rate was less than 4% only 4 years since rates started being tracked in 1920, and those were during WWII and the 2 years following. That is understandable with so many people in the armed forces, and so many died.
So, any unemployment rate between 4-5% is "full employment". And when you reach full employment, it is IMPOSSIBLE to create more jobs, because there are no people to fill those jobs.
When Romney was governor of MA, he brought the unemployment rate to 4.6% (from a high of 6%) - full employment. Even Jesus could not have created many more jobs. And if you cannot create any more jobs because everyone is already working, you end up 47th of 50 in job creation (but as you will see from a study by Politifact, his term ended with MA 30th out of 50, not 47th).
So the real story - if you are 47th of 50 with an unemployment rate of 8%, you are doing lousy. But when you are 47th of 50 and you have full employment, you have done exceptionally well.
But the Democrats don't tell you that everyone in MA had a job. Nope! They would rather throw out a statistic taken out of context in order to mislead you.
In fact, Politifact checked the records and actually found that from December 2002 to December 2003, the job growth in Massachusetts was 51st highest nationally out of 50 states plus the District of Columbia -- in other words, dead last. The following year, it was 46th, then 40th, then in Romney’s final year in office -- December 2005 to December 2006 -- it was 30th in the nation. For each year Romney was in office, the unemployment rate went down - FAST.
That's what they do. Pay attention.
