All of the talk about past and future convention public opinion “bounces” is interesting, but there has been far too little attention to a potentially crucial development that could impact the Democratic convention bounce (if there is one), and the entire presidential race in the next two weeks.

This year, President Obama will accept his party’s nomination on Thursday, September 6. But less than 12 hours after the president concludes his speech, on Friday, September 7, at 8:30 am Eastern Time, the Bureau of Labor Statistics will release the August unemployment rate and new jobs numbers. Those could have a huge impact on the race for president, overshadowing Obama’s speech and the entire Democratic convention.

A strong jobs report surely would boost the president’s numbers and prospects, adding to any momentum from his party’s convention, just as very weak numbers could turn the race from a toss-up or one in which Obama holds a slight advantage to one…
