For any of my readers who have thought about what it means to be a TCK or parent one--here's an interesting quote from WORLD Magazine (Online):

Both presidential candidates Barack Obama and John McCain are adult third culture kids, spending developmental years outside their passport cultures. Obama lived in Indonesia with his stepfather and mother. McCain was born in the Canal Zone and grew up as a military child in the Pacific...

...Third culture kids, like many homeschoolers, [Van Reken] writes, often have stronger relationships with adults. They can be perceived as arrogant—a charge slapped against both Obama and McCain. The world usually looks different to them because of their multicultural experiences. Many third culture kids develop a sense of a both/and identity rather than the traditional either/or identity common to those growing up in one culture.

"Obama is one of the millions of people across our globe who grew up among many different cultural worlds," Van Reken argues. "Ironically, among the common characteristics of these third culture kids is the capacity to be cultural bridges, to be able to see both sides of a situation."

And McCain? "He is seen as a maverick," she says, "because he frequently won't stay in his assigned box and has often voted across party lines."
