Travelers recognize that the results of an election here in the US can have a greater impact on poor people half a world away than it does on middle-class American voters. My travels have taught me that, even if motived only by greed, you don't want to be really rich in a desperately poor world. With this in mind, I think of it not as noble or heroic, but simply pragmatic to bring a compassion for the needy along with me into the voting booth.
