From the NYT:
Analysts say the Bersih campaign could help the political opposition.
"The opposition parties have jumped on this bandwagon because they would be direct beneficiaries of electoral reform," said Ibrahim Suffian, director of the Merdeka Center, an independent polling firm in Kuala Lumpur.
Describing Bersih's demands as "perfectly normal in terms of what's expected in a functional democracy," Mr. Ibrahim said that if large numbers of protesters turned out Saturday, it could slow the government's momentum after a recent series of by-election victories.
"I think that is the deeper concern: that a show of protest, a show of force by the opposition and NGOs demanding reforms from the government, could sway undecided people to feel that the government is not doing enough," he said.
Ong Kian Ming, a political analyst at UCSI University, said that the rally came at an "opportune time" for the opposition and that a violent crackdown on the protesters could be "a game changer" in the coming elections.
