The editorial was a stern reminder of Mr. Romney’s failure to win the trust of the Republican Party’s core conservatives, a group that pays close attention to Mr. Murdoch’s newspapers and cable news outlets. Though political strategists debate the ultimate impact of any single media outlet, what is written in the pages of The Journal and The New York Post and talked about on Fox News — all Murdoch properties — could have the collective power to shape the thinking of millions of voters.

Mr. Murdoch’s dim view of Mr. Romney points to a palpable disconnect between the two men, one that has existed since Mr. Romney’s first run for president four years ago, people who know them both said. More than a half-dozen friends and advisers to the two, speaking mostly anonymously to reveal private and frank conversations, said the Murdoch-Romney relationship could be summed up simply: They do not have much of one.

They have met only a handful of times. Their lukewarm feelings toward each other stem from their encounter at a meeting of The Journal editorial board in 2007, when Mr. Romney visited to pitch himself as the most capable conservative candidate about two months before the Iowa caucuses.

Romney and Journal staff members who attended said that despite being deeply prepared and animated — particularly on his love for data crunching — Mr. Romney failed to connect with either Mr. Murdoch or The Journal’s editorial page editor, Paul A. Gigot. Instead of articulating a clear and consistent conservative philosophy, he dwelled on organizational charts and executive management, areas of expertise that made him a multimillionaire as the head of his private equity firm, Bain Capital.

At one point, Mr. Romney declared that “I would probably bring in McKinsey,” the management consulting firm, to help him set up his presidential cabinet, a comment that seemed to startle the editors and left Mr. Murdoch visibly taken aback.
