Seven candidates contested the election. Abbas won over 62% of the votes cast, with independent Mustafa Barghouti coming second, on just under 20%, and the remaining candidates far behind.
The election was boycotted by Hamas and Islamic Jihad. In the Gaza Strip, where Hamas is strongest, it is estimated that about half of the eligible voters voted.
After successive contradictory announcements, Marwan Barghouti declared his candidacy just before the registration deadline expired but then retired from the race on December 12 after discussions between his representatives and the Fatah leadership. With his withdrawal, Mahmoud Abbas was seen as the clear favourite, with Mustafa Barghouti in second place.
Opinion polls before Marwan Barghouti withdrew his candidacy suggested that the contest would largely be a two-horse race between him and Mahmoud Abbas. Details of some of these polls are as follows:
Three other candidates who registered by the end of the registration period subsequently withdrew: they were Marwan Barghouti, Hassan Khreisheh and Abd al-Sattar Qasim.
Many of Abbas' opponents claimed that they were unfairly treated as Israel denied them entry to areas Abbas was allowed to visit during the election campaign. Abbas was the only candidate allowed access to Gaza.
There were also some technical problems including those due to the incomplete electoral register. Persons not listed on the electoral register were permitted to vote on presentation of a valid identity card. Voting was controversially extended for two hours beyond the appointed closing time, apparently at the request of Fatah; the head of the electoral commission subsequently resigned in protest. The election was observed by number of international observers included former President Jimmy Carter and U.S. Senators Joe Biden and John E. Sununu.
The European Union's foreign policy chief Javier Solana criticized Israel for obstructing the Palestinian presidential election. He was quoted as saying that "We expected the Israelis to offer more facilities for the Palestinian election process but they did not live up to promises."

At the end of polling, the Head of the CEC, Dr Hanna Nasir, told the media that "Approximately seventy per cent of registered voters voted today ... While approximately only ten per cent of unregistered voters turned out."
The CEC had made enormous efforts to register all eligible Palestinian voters in the run up to the election, but almost a third of eligible voters did not register or were unable to register. In an effort to boost low turnout, the CEC made a highly contested decision in the final hours of polling day to allow unregistered voters to cast ballots using only their identity cards, which raised fears of multiple voting. A Palestinian election official, speaking on condition of anonymity, told the Associated Press that the changes came after heavy pressure from Mahmoud Abbas' Fatah movement, which feared a low turnout could weaken Abbas.

The day before the election the total number of registered voters was 1,092,407 according to a CEC press release. ("Central Elections Commission (CEC) Upcoming Presidential Elections: Facts and Statistics," CEC, 8 January 2005)
However, in a November 23 statement, the CEC explained: "The number of registrants on the voters’ list reached 1,111,868, or 67 percent of the estimated number of eligible voters, during the registration process conducted between September 4 and October 13, 2004. Of these names, 19,000 were removed from the voters’ list because the accompanying data was incomplete or the names were repeated on the list. With this adjustment, the number of registered voters decreased to 1,092,856." ("46% of Registered Voters are Youths, 46% are Women," CEC, 23 November 2004)
