Samira Muhammad's vote is as much about revenge as anything.
Seated on the doorstep of her bullet-riddled home on the southern tip of the Gaza Strip, she gestures at a house on the opposite side of the street flattened by Israeli armour when the tanks still used to crash in to Khan Yunis refugee camp. However, the target of her ire is not the Israelis but the Palestinian government.
"Nobody came to clear that house. Our children are playing in the rubble. They fall and hurt themselves. It's typical of Fatah and the Palestinian Authority. They don't do anything. Maybe Hamas will. I'm sick of Fatah. There is so much corruption," said the mother of seven, who is 35.
Criticism of the Fatah movement, which has governed the Palestinian territories since the last election 10 years ago, has been common on the streets of Gaza for years. But with Palestinians voting tomorrow in the first national election in which there is a genuine contest for power, the attacks no longer go unchallenged. The party colours bunched like flowers on lampposts, the posters of bearded faces plastering almost every public space and the parade of deafening loudspeakers through the streets testify to the hard struggle for votes once taken for granted.
Opinion polls suggest that Fatah, the movement founded by Yasser Arafat, is fighting to stave off Hamas, the armed Islamist group. Fatah still looks likely to come out on top but without an outright majority, and that will probably mean sharing power. The polls say that rampant corruption, nepotism and mismanagement are the main factors in the draining away of support from Fatah.
Hamas has made much of it in television commercials built around the usual scenes of explosions and shooting but now directed against the Palestinian Authority's shortcomings. One advert opens with the word "corruption". It swiftly explodes into a ball of fire followed by a similar fate for nepotism, bribery and chaos. Only then come the pictures of Palestinian gunmen fighting Israeli forces in Jerusalem and Nablus, followed by scenes of wounded Palestinian children.
"We want to vote for someone who is poor like us, who feels for us," said Mrs Muhammad. "For 10 years Fatah haven't done anything for us. We have to try Hamas. We can't say if they will be better but we have to try."
There are many on the streets of Khan Yunis who feel that Hamas can only be worse. For a start, a Hamas-run government is less likely to reach a peace agreement with the Israelis.
"What are our real problems? Unemployment and the economy. They cannot be solved without negotiations with the Israelis," said Fathi Rantisi, a 25-year-old computer engineer and Fatah voter. "Hamas don't want to deal with the Israelis but we have to whether we like it or not. They are the people we have to make peace with."
But there is a recognition among Fatah voters that many of the party's existing leaders are discredited as corrupt or incompetent. "This is the most important issue in Fatah now, to change the leaders," said Salam Abdel, a Fatah supporter. "But corruption is everywhere because we are living in very difficult times. If there was peace with the Israelis there wouldn't be the corruption. Anyway, do you think Hamas won't be tainted by corruption? We'll see how they do in parliament."
Salim al-Agha, a 53-year-old engineer, was most concerned about growing insecurity on the streets amid factional and clan violence. He was not keen to say how he intended to vote but did want to see Fatah and Hamas sharing power after the election.
In Gaza, Fatah's campaign is led by the local strongman - some prefer to call him a thug - Muhammad Dahlan. He is riled by Hamas's attempts to claim that it has led the armed struggle and driven the Israeli army from Gaza. Mr Dahlan invoked Arafat's name and mocked Hamas at a final election rally yesterday in Khan Yunis, where he is fighting for a seat in parliament. "Hamas accused Arafat of betraying the people and destroying Palestine [by reaching the Oslo accords with Israel]. But here they are taking part in elections because of what Arafat agreed. They should apologise to Fatah and admit that our plan triumphed," he said.
Earlier Mr Dahlan led a rally outside Arafat's old house in Gaza City yesterday. Fatah is reminding voters that long before they had heard of Hamas, Arafat was shooting at Israelis. A giant banner on the side of the house might at first glance be mistaken for an advert for an action film. Just like Hamas posters, it featured rockets, explosions, masked men with guns.
"We are the ones carrying the olive branch and the gun," said one Fatah speaker, Fuad Madi. "We are the ones who fought first. We are the ones who used the first stones and the first bullets. We wrote our struggle with blood."
Then the audience were asked to raise their hands and swear in the name of God, the dead and the prisoners to vote for Fatah.
Mr Dahlan has told rallies across the Gaza Strip that things will change, that Fatah is reforming, that the corrupt old guard is on its way out.
Mrs Muhammad is not persuaded. "Dahlan came here and promised us he would do this and that. We don't believe him. We heard it before," she said.
