ANCHORAGE - In late March, a senior official from the Republican Governors Association headed for Alaska on a secret mission. Sarah Palin was beset by such political and personal turmoil that some powerful supporters determined an intervention was needed to pull her governorship, and her national future, back from the brink. The official, the associations executive director, Nick Ayers, arrived with a memorandum containing firm counsel, according to several people who know its details: Make a long-term schedule and stick to it, have staff members set aside ample and inviolable family time to replenish your spirits, and build a coherent home-state agenda that creates jobs and ensures re-election. Like so much of the advice sent Ms. Palins way by influential supporters, it appeared to be happily received and then largely discarded, barely slowing what was, in retrospect, an inexorable march toward the resignation she announced 10 days ago.
