• Viewers would need to pay close attention to the on-screen graphic to know that the ad refers only to employment gains starting in March 2010, omitting the 4.3 million jobs that were lost in the first year of Obama’s term.
• And there’s no way a viewer would know that the total counts only private-sector jobs, omitting continuing losses in government employment.

According to the most recent employment figures from the Bureau of Labor Statistics, the economy has eked out a net gain of 325,000 jobs since January 2009, when Obama took office. And that’s giving credit for roughly 386,000 jobs that the BLS has announced, on a preliminary basis, that it will be adding to this year’s employment totals next year, as a result of its routine annual “benchmarking” analysis.
