I think you are somewhat right but the correct answer to the question would've been "I don't really think that is the case.". If somone asks me if it is possible my friends are secret racists I'm certainly not going to respond by saying it's possible. Maybe a "I sure do hope not." but I wouldn't give credence to something I knew to be most probably false. The left doesn't need headlines and the GOP doesn't need to use the language of the left to defend itself. I like Laura Bush and I'm sure the question was a setup as most are but I don't think it is wise feed such ideas especially if you want to gain support for your nominee.
