I hate Obama. I hate him worse than I hate Jay Jacobs and Gene Chizik combined.
That said, GWB is the only president I have ever met personally. I saw Reagan speak, but when Bush was campaigning in 2000, I had the opportunity to meet him in a relatively intimate setting. Not a speech, but a meeting with about nine or ten other people in my then-bosses conference room.
I've got to say he was easily the dumbest person in the room. I've never been less impressed with anybody in my life.
