The ad starts with a tipped-over fish bowl, and a goldfish that washes out onto gravel, flailing.
"This is the economy on stimulus," the girl continues, as the near-dead fish is covered in dirt. "Any questions?"
The ad was posted on sickofstimulus.com and created by Cain Solutions, Cain's economic post-campaign project, to point out what he deems the ineffectiveness of economic stimulus.
But while it is clear in its message that different economic solutions are needed, the ad gives little direction or explanation as to the specific problems of economic stimulus.
"The goldfish is fine, but our economy isn't," reads the description on the ad's YouTube page. "Are you Sick yet? In essence, stimulus has been just like throwing a bucket of water on a fish and expecting him to swim on land. We want Solutions, not more Stimulus coming from Washington D.C."
The Congressional Budget Office said earlier in February that Obama’s 2009 stimulus package continues to have a significant effect.
The bill raised fourth-quarter 2011 gross domestic product by as much as 1.5 percent, it states, and lowered the unemployment rate by as many as 1.1 percentage points.
Cain is the latest in the ranks of politicians to use children to enhance their political message. Earlier this week Rhode Island Senate candidate Barry Hinckley (R) employed his 5-year-old son to point out the failings of "career politicians."
