Have the Dems found any ligit experience Obama has for President?

I had to laugh at the Dems that were interviewed during the DNC. When they were asked what experience Obama had they couldn't give those answers and had to dodge those questions and it was obvious. Now the Dems are attacking Palin's experience and she's not his opponent. Mccain and Palin are real change. Obama is clueless and Biden is old Washington and he has a corrupt past and we have already told Biden we don't want him. His own party made that clear.
