Sarah Palin (right) celebrated the US Independence Day with her family
Sarah Palin has hinted she might take on a wider political role in the US, one day after abruptly announcing she was resigning as governor of Alaska.
"I am now looking ahead and how we can advance this country together," she wrote on her Facebook page.
The former Republican vice-presidential candidate said earlier she would resign as Alaska governor on 26 July.
There have been speculation that she might be preparing to make a bid for the White House in 2012.
But the fact Mrs Palin did not reveal what she intended to do after leaving office, and did not give an explicit reason for her decision not to run for re-election, prompted speculation there might be another reason for her stepping down.
One report on NBC news suggested that Mrs Palin intended to get out of politics "for good".
In her Facebook posting, Mrs Palin said she urged Americans to "join me" in looking how "we can advance this country together with our values of less government intervention, greater energy independence, stronger national security, and much-needed fiscal restraint".
"Now is the time to rebuild and help our nation achieve greatness!" she wrote.
On Friday, Mrs Palin said that she had decided to resign as governor after "prayerful consideration that sacrificing my title helps Alaska most".
She also said that "we have accomplished more during this one term than most governors do in two - and I am proud of the great team that helped to build these wonderful successes".
At the same time, she said the response in the media to her surprise announcement was "most predictable" and "detached from the live of ordinary Americans".
"How sad that Washington and the media will never understand; it's about country," Mrs Palin wrote.
The governor's spokeswoman, Meghan Stapleton, confirmed that Mrs Palin had written the posting, the Associated Press reports.
Polls indicated Mrs Palin was very popular in Alaska during the first few years of her governorship, and although her approval ratings have dipped somewhat since her vice-presidential run, she still enjoys widespread popularity in her home state.
She is also popular with the Republican Party base, analysts say.
