Here's Romney poking a bit of fun at Obama:
Obama has only himself to blame for questions about his eligibility for office. His own bio for his publisher claims he was born in Kenya and questions persist as to whether he requested special consideration for admission to Columbia and Harvard as a foreign exchange student since he won't release those records.
Note that Romney offered up this jab in a light hearted way. He didn't have his campaign accuse Obama of being a felon who tortured his dog (Obama ate his dog) and didn't pay taxes!
