I think the Hillary one looked slightly more deliberate, and certainly the woman behind him thought so. I am not sure even that one was deliberate, though one could tell he did have animosity for Hillary in the primaries.
But I don’t think he was flipping off McCain here. I could be wrong though, but I doubt it.
So I guess he just rubs his face with his middle finger when he’s talking about Hillary or McCain. Sure, okay.
