Obama for America, "Endorsed" 

What it says:  "He served America as a four-star general, as secretary of state. Here's Republican Colin Powell on CBS." The rest of the ad is just audio of Powell praising President Obama's economic and foreign policy record. 

What it means: This one's pretty straightforward. Powell has always been popular, and even if his endorsement doesn't carry the symbolic weight it did in 2008, he's still a well-liked, trusted Republican endorsing a Democratic president.

Who will hear it: Florida, Wisconsin, North Carolina, Virginia, New Hampshire, Ohio, Iowa, Nevada, and Colorado.
