Yes, you had to walk through customs and get your passport stamped. But did you also notice the American stamper typing your name into a computer? I'm not sure that there is a master file that records everyone's travels.
Just to get a general feel, how does this come down, bad for GOP, bad for Klintoon, or bad for Obama (although he’ll play the victim anyway)?
Don't know about you, but they swipe the main page of my passport through a reader upon entry. Okay -- they have departure and itinerary info when I leave, but that's it. They do NOT look to see where I've been when I return; my passport is full enough of stamps that that would take fmore than the minute or two Immigration spends on me.
