Script For "Our Home" (TV:30):
ANN ROMNEY: "We have five boys – five boys and ten grandkids. Big family.
"Mitt says his greatest success is being able to say 'I have been a good father, and a good husband.'
"Sometimes I'd be home with those five boys, and it was rough.
"He'd call home and remind me that what I was doing was much more important than what he was doing.
"Mitt says there's no work more important than what goes on within the four walls of the American home. And that's the way it was in our home.
"I'm Ann Romney."

Kennedy won the West Virginia primary and went on to the presidency."
