From a microphone on the muddy lawn, a student complains to the politicians on stage about rising joblessness.
An older man asks what they will do about Cambodia's entrenched corruption.
A young mother, memories of war and destruction still fresh in her mind, demands to know if any of their parties will instigate violence if they lose in the upcoming election.
It's democracy in action, as Cambodia prepares for national polls on July 27 to select who will lead the country as it continues to claw its way out of the wreckage of decades of strife.
Up for grabs are 123 parliamentary seats. Some 6.2 million people -- out of a population of 12.5 million -- are eligible to vote for the party they believe should lead the government for the next five years.
Politics here is often regarded as a spectacle to break the everyday routine, with rallies heralded by noisy loudspeakers on cruising trucks.
But for the first time in a national election -- the third since multiparty democracy was restored in 1993 -- voters who are getting a chance to grill the candidates in debate-style at public forums.
``Such an event is absolutely important in helping me make my decision,'' says Yeang Bun Yol, a 24-year-old student.
This particular debate in Battambang province, 250km northwest of the capital, is being held on the grounds of a Buddhist temple, a traditional community gathering place. It is one of a dozen planned for several provinces with candidates from 14 of the 23 contesting parties.
Monks chant blessings for the three candidates before they climb onto the stage. About 2,500 people sit on the surrounding lawn, defying light rain followed by blazing sunshine to hear what the candidates have to say.
Debating policy is encouraged, attacking personalities is out of bounds, according to the rules set out by the debates' organizer, the US-based National Democratic Institute.
``Personal attacks here are cause for concern; they could make bad things happen here,'' says Kelley Jones, a senior official from the institute, an arm of the Democratic Party in America which is intended to encourage democracy worldwide.
Violence has marred past Cambodian campaigns, and seven political activists have been killed since the current campaign started last month.
While both the National Democratic Institute and a visiting UN delegate have complained about intimidation fom some of the candidates in the campaign, the institute said the situation had improved from past elections.
At the Battambang rally, candidates from the election's main contenders -- the ruling Cambodian People's Party, its junior coalition partner Funcinpec, and the opposition Sam Rainsy Party -- take turns fielding questions from a moderator, each other and finally, three members of the audience.
Funcinpec candidate Nhek Bun Chhay says that should his party win, it will deal decisively with illegal immigrants, meaning primarily ethnic Vietnamese whose presence historically causes nationalistic resentment among many Cambodians.
Playing the race card is an ugly but familiar -- and usually productive -- tactic in Cambodian politics.
Eng Chhay Ieng, the candidate for the Sam Rainsy Party, makes sure to mention ``corruption'' in his answer to almost every question.
Party leader Sam Rainsy, a former finance minister who once was with Funcinpec, made his name as an outspoken foe of corruption. It's a good fit for his party, whose position as the sole parliamentary opposition already makes it a natural magnet for the disgruntled.
