In 2005, I took the Amtrak from the west coast to the east. This was just before Katrina, when the Sunset Limited went through New Orleans. It didn't end there, as it does now.
Along the way, the route practically kisses the fences at the Mexican border.
I took pictures.
They're our next door neighbors and you can actually see Mexico from the lower 48, from a train chugging through Texas.
This provides me with extraordinary insight into our neighbors to the south, and proves without question my foreign policy credentials.
Furthermore, approaching New Orleans I saw a number of graveyards, which provides me with extraordinary insight into the afterlife and only deepens my foreign policy experience.
Furthermore, this is not the first time I've qualified for higher office. Excuse me now while I go pack for DC. Just let me know when the limo is coming.
