Real Clear Politics reports that Sarah Palin has quit her bus tour halfway through, thus continuing the undefeated streak that she began when she bravely quit her position as governor halfway through her first and only term:

In an apparent repudiation [sic; that should obviously be "refudiation"] 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.

There's no way she's running for president.
