How many times was her father married, anyway?  This is not the same half sister who was angry that Cindy McCain lied about being an only child-THAT daughter, who supports Obama, has a yet different mother.

Dixie Lea Burd, 74, shared a mother with the wife of Republican presidential nominee and Sen. John McCain, R-Ariz. Their mother, the late Marguerite "Smitty" Johnson, married Cindy McCain's father, the late Jim Hensley, on March 29, 1945.
