A "manipulation" post--what does that mean?

It's possible that a husband and wife know each other enough to know how each other would react in a given situation.

Cindy said that "... the maverick senator immediately accepted his new daughter."
Media Matters - NY Daily News : "[M]averick" McCain "immediately accepted" adopted daughter
It's interesting that when wealthy Angelina Jolie adopts third-world babies everyone praises her. But when a conservative wealthy woman adopts a third-world baby with a birth defect she gets all kinds of criticism.
The arrangement worked out well for them so why be shocked? Just because you or I might do things differently than the McCains doesn't mean we're "right" and they're "wrong."
