Rupert MurdochThe News Corp CEO kicked a hornets’ nest a few hours ago with this post: “Scientology back in news. Very weird cult, but big, big money involved with Tom Cruise either number two or three in hierarchy.” He was back soon afterward: “Watch Katie Holmes and Scientology story develop. Something creepy, even evil, about these people.” One responder wanted to know what he thinks about Mormons, to which Rupert said: “Mormonism a mystery to me, but Mormons certainly not evil.” The comments had a predictable effect: “Since Scientology tweet hundreds of attacks,” Rupert writes. “Expect they will increase and get worse and maybe threatening. Still stick to my story.”

Murdoch appears to be more ambivalent about GOP presidential candidate Mitt Romney. “Met Romney last week,” Murdoch says. “Tough (Obama) Chicago pros will be hard to beat unless he drops old friends from team and hires some real pros. Doubtful.” That followed a similarly critical tweet last week. “When is Romney going to look like a challenger? Seems to play everything safe, make no news except to burn off Hispanics.” Still, in today’s tweets Murdoch seems to agree with Romney’s view of the main question in the race. “US election is referendum on Obama, all else pretty minor.” Asked how much capital he has donated to Romney, Rupert says “None!” Someone else noted that “There will be no phone tapping in US election,” adding that “your folks” messed up the economy and now “expect overnight fix.” Rupert answered: “my folks! Come off it, let’s have serious discussion.”

On a side note, one follower wanted to know when Murdoch might bring his son, Lachlan, back into the upper echelons of the company calling him “the most effective and well-respected executive in Australia.” Rupert’s response: “Thank you, the door will always be open for him.”
