An entrepreneur has decided to "have fun" with the US presidential campaign by marketing condoms featuring images of the candidates, Democrat Barack Obama and Republican John McCain. Benjamin Sherman, who created the company Practice Safe Policy, says the Obama condom carries the slogan "Use With Good Judgment." The McCain version says "OLD BUT Not Expired." McCain is 71. According to the Web site, McCain condoms "are battle tested, strong and durable, for those occasions when you just need to switch your position!" McCain served in the military in Vietnam and was held as a prisoner of war there. While the company can't guarantee the condoms are 100 percent effective, it says it's certain "that without wearing one, there's likely to be an Obama-Mama in your future."
