In a hastily arranged news conference at her home in Wasilla, a suburb of Anchorage, Palin said she had decided against running for re-election as Alaska's governor, and believed it was best to leave office even though she had 1.5 years left to her term. Lt. Gov. Sean Parnell will take her place.
"Many just accept that lame duck status, and they hit that road," Palin said. "They draw a paycheck. They kind of milk it. And I'm not going to put Alaskans through that."
Palin has proven formidable among the party's base. But the last week brought a highly critical piece in Vanity Fair magazine, with unnamed campaign aides questioning if Palin was really prepared for the presidency.
The backbiting continued with follow-up articles elsewhere recounting the nasty infighting that plagued her failed bid. Her advisers sniped with other Republicans, underscoring the deeply divided GOP looking for its next standard bearer.
Meghan Stapleton, Palin's personal spokeswoman, shot down speculation that ranged wildly from Palin dropping out of politics altogether to eyeing runs against fellow Alaska Republicans Rep. Don Young and Sen. Lisa Murkowski. Palin's comment about serving outside government refers to the present, she said.
Stapleton, however, said it's too early to say whether Palin would seek the presidency. In the meantime, the governor will continue to work to bring "positive change as a citizen without a title right now," she said.
"Her vision is what's best for Alaska, which translates into what's best for America," Stapleton said.
Murkowski, whose father was the governor when he lost to Palin in the 2006 Republican primary, was dismissive of the announcement.
