Also in the issue of BusinessWeek discussed below, Kristen Hinman and Cynthia Hoffman compare an Obama speech in St. Petersburg, Florida from August 1, 2008, to one he delivered in Orlando on August 2, 2012.

It will not surprise you that the 2012 version has fewer specifics, no longer refers to “green jobs,” now emphasizes “cut away spending we don’t need,” and mentions Mitt Romney 18 times. Four years ago, Obama mentioned McCain only 10 times.

Obama uses the word “tax” more, from 17 times to 25 times; references to “Bush” are the same: 4 in each speech.

Perhaps most notably, back in 2008, when the unemployment rate was only 5.7 percent, Obama used the word “economy” 15 times. Now, with unemployment 8.3 percent, the word “economy” appears in Obama’s speech only 7 times.
