In an interview scheduled to air Sunday on ABC's "This Week with George Stephanopoulos," the would-be first lady said repeated references to her husband's comment that he didn't know how many homes the couple own were unfair. She said Democratic nominee Barack Obama went too far in his acceptance speech in Denver Thursday when he said John McCain doesn't know what middle class working families have to deal with.

"I'm offended by Barack Obama saying that about my husband," Cindy McCain told ABC.

She argued that her family's road to wealth, through the beer distributorship her father founded, represents the American Dream.

"I'm proud of what my dad and my mother did and what they built and left me," she said. "And I intend to carry their legacy as long as I can."

Obama campaign spokeswoman Linda Douglass told ABC the issue "isn't wealth of the McCain family, it's that Senator McCain is out of touch when he says that the fundamentals of our economy are strong' and that the Bush economy has 'made great progress' when most Americans are actually losing ground."
