Undated (AP) Rosanne Cash wants her late father Johnny Cash left out of the presidential campaign.

She's putting people on notice after John Rich implied Johnny Cash would have backed John McCain. She writes on her web site that “it's appalling” that people want to use her father's name “to ascribe beliefs, ideals, values and loyalties to him that cannot possibly be determined, and to try to further their own agendas by doing so.”

The Washington Post reports that at a pro-McCain concert earlier this month, Rich declared: “I'm sure Johnny cash would have been a John McCain supporter if he was still around,” before he played Cash's “Walk The Line.” Rosanne Cash says she knew her father pretty well and that “even I would not presume to say publicly what I 'know' he thought or felt.” she says, “it is unfair and presumptuous to use him to bolster any platform.”
