Palestinian politicians are making their pitch on the final day of the campaign before Wednesday's election.
The ruling Fatah party faces an unprecedented challenge from the Islamic resistance group Hamas, which is standing for the first time.
Israel and the US say they will shun a government if it includes members of Hamas which they see as a terror group.
Nearly 1.5m Palestinians are eligible to vote at about 1,000 polling centres in the West Bank and Gaza Strip.
Candidates with loudspeakers have been cruising the streets drumming up support, while supporters plastered more posters on the graffiti-covered walls of Palestinian towns.
Fatah has held a rally at the Gaza home of late leader Yasser Arafat, while a Hamas political leader has raised the possibility of negotiations with Israel.
Slogans
‘With one hand we will build, with the other we will fight,’ declares one Hamas poster seen in the West Bank city of Hebron.
The group also exploits its controversial international reputation to ask Palestinians: ‘Israel and American said no to Hamas. What do you say?’
Hamas does not recognise Israel and has launched hundreds of attacks against its citizens both in Israel and the occupied territories.
However, a senior Hamas official in Gaza, Mahmoud Zahar, said the group was not against negotiations with Israel if they produce tangible benefits.
‘Negotiations are a means. If Israel has anything to offer on the issues of halting attacks, withdrawal, releasing prisoners ... then 1,000 means can be found,’ he told reporters.
Fatah posters, meanwhile, claim the accolade ‘the first to launch the bullet and to resist the occupation, and the first to launch democracy’.
The party wrapped up its campaign with a Gaza rally intending to evoke the memory of the controversial Mr Arafat, who remains a powerful symbol for many.
‘The election will be a victory for Fatah... for women, for Yasser Arafat's soul and for all of Jerusalem and for all our martyrs,’ senior Fatah figure Muhammad Dahlan told thousands of supporters in Khan Yunis.
Election monitors, including ex-US President Jimmy Carter, have received assurances from Israel's interim PM Ehud Olmert that military checkpoints in the West Bank will be ‘as open as possible on election day’.
Israeli military sources say Israeli troops will refrain from all but what they termed ‘essential operations’ during voting.
Boycott
BBC correspondent Matthew Price in the West Bank city of Nablus says many voters there are talking about the need for a change from Fatah, which is widely seen as corrupt.
Hamas meanwhile is seen as a national liberation movement which is legitimately fighting Israeli occupation, our correspondent says.
Palestinian security forces have already begun casting their votes so they can guard polling stations on Wednesday.
A policeman voting in Gaza told reporters it was better to stick with the current leadership.
‘With Hamas, we are heading into the unknown... They are just giving us slogans while killing our colleagues,’ he said, referring to past clashes in Gaza City.
On Sunday, US officials confirmed that Washington had directed money to promote ‘democratic parties’ in the election including Fatah, a move that violates election law. But they denied the funding was intended to undermine Hamas.
A statement from the militant group Islamic Jihad called on supporters to boycott the vote, although it was not expected to make a major difference, correspondents said.
