That too is a good question. As a Malignant Narcissist, Obama would lie with every single answer he gave...BUT, he would also get angrier and angrier. MNs do not like to be questioned or challenged. Normally he makes sure he’s never in a venue where this can happen. If you won dinner with him, though, he couldn’t very well storm out after ten minutes, nor could he order you to be ejected just for asking questions.
It could make for an interesting night.
