Mahmoud Abbas, president of Palestine and head of Fatah, was the one to suspend both legislative and presidential elections and not Hamas. In fact, the latter “strongly opposed the decision to call off elections” (npr.org).

Abbas' party has been working closely with the Israeli authorities. His excuse was that “Israel refused to commit to allowing Palestinians to vote in Israeli-occupied East Jerusalem” (npr.org).

Some (quite convincingly) hypothesise that the suspension of the elections was aimed at preserving his presidency and salvage “his fractured Fatah party [which] was expected to suffer another embarrassing defeat to Hamas.” (apnews.com).

How can one expect the people to not fight if democracy can't be exercised freely?
