Former Alaska governor Sarah Palin has canceled a trip next month to war-ravaged Sudan, one of the most unstable nations in the world and the focus of passionate advocacy within the U.S. evangelical community.

Palin scrapped her visit to the North African country for scheduling reasons, several sources close to her said. She was planning to travel with Franklin Graham, the son of evangelical leader Billy Graham, as well as Fox News personality Greta Van Susteren to the July 9 independence ceremony of South Sudan, the sources said.

The decision comes at a time when speculation is mounting about whether Palin will seek the Republican presidential nomination. Her weeks-long silence since the end of her One Nation bus tour along the East Coast has prompted a raft of questions about whether there will be a second or third leg, as advisers initially said there would be, through the Midwest and the South.

Palin weighed in on the debate via Twitter on Wednesday afternoon, tweeting “I did?” in response to several headlines reporting that she had canceled the tour.

In the meantime, she is in Alaska enjoying what she has described on her reality TV show, “Sarah Palin’s Alaska,” as her family’s favorite time of year. This is when the Palins typically travel north for an annual salmon fishing trip to Bristol Bay.

But, here is the tweet from Sarah:

So, who knows?

But, it is increasingly looking like she won’t be running for President in 2012.

And, you know, if she enjoys the summer in Alaska and doesn’t make any further announcement regarding her Presidential intentions that is really her business. She will announce what she wants to announce, when she wants to announce it.

You betcha on that one.

Less than a month after she appeared poised to shake up the Republican presidential campaign, former Alaska Gov. Sarah Palin has once again receded from the 2012 limelight.

When Palin launched her “One Nation” bus tour on Memorial Day amid a swirl of media attention and excitement from her fervent fan base, many political observers who had once dismissed her were reminded of the jolt that her candidacy could provide to what has thus far been a relatively sleepy GOP nominating fight.

As Palin toured historical sites along the East Coast, she was clearly reveling in the tangible excitement she’d ginned up: She even eagerly answered questions — from the denizens of the “lamestream” media — ranging from matters of political process to an array of issues facing the nation.

In an apparent repudiation to those who dismissed her trip as a mere publicity stunt, Palin’s openness with reporters about her intentions to visit Iowa and South Carolina — in addition to her highly scrutinized stop in the first-in-the-nation primary state of New Hampshire — lent credence to her repeated assertions that she was indeed seriously considering a White House bid.

Though Palin and her staff never announced a timeline for the remaining legs of her trip, aides had drafted preliminary itineraries that would have taken her through the Midwest and Southeast at some point this month. But those travel blueprints are now in limbo, RCP has learned, as Palin and her family have reverted to the friendly confines of summertime Alaska, where the skies are currently alight for over 19 hours a day and the Bristol Bay salmon fishing season is nearing its peak.

As Palin enjoys her sojourn to the 49th state, she has not reconnected with key early-state figures like Iowa Gov. Terry Branstad and South Carolina Gov. Nikki Haley, and she may have jeopardized whatever political momentum she gained from her recent reemergence in the 2012 discussion. Her political action committee’s website still greets visitors with a stale banner, announcing the nationwide bus tour beginning “[t]his Sunday, May 29th.”

Looks like Sarah will NOT be running for President.

Maybe it was the polling that showed her losing handily to President Obama or the emergence of Michele Bachmann? In any case, she has not quit or been relieved of duties from Fox News and there is little buzz in Arizona where she purchased a home.
