Problem is, even the Obama water carriers know that the claim about Romney is horseshit.
When Romney took office, MA was LOSING jobs and was ranked 50th out of the 50 states (not 57, Obumbles.)
If you go year-by-year instead of looking at the entire four year period (his first year, MA lost 60K jobs) they went from 50th to 28th. Now OVERALL, yes, it's true that would put MA 47th in that four-year span, but also ask yourself, who RUNS Massachusetts?
