___CHALLENGES AHEADHamas and Fatah have spent years trying to reconcile after a split more than a decade ago. Rights groups have accused both of suppressing political opposition. Zuheir al-Khatib, a 57-year-old doctor from Bethlehem, was more optimistic. While he has repeatedly said he would not seek another term as president, he has not groomed a successor. Both sides have been unwilling to cede power and compromise  and its not clear whether attitudes have changed.
A victory by the Fatah would complicate the CAMPAIGN.
