COMMENT | The voters in Tanjong Piai delivered the worst loss for an incumbent government in a federal by-election in Malaysian history this weekend.
It was also another first: this was the highest level of swing against Dr Mahathir Mohamad in his two tenures as prime minister in any election (including the reformasi swing of 1999).
Across races, generations and genders, voters not only protested, they also sent a clarion call that Mahathir, his party and his coalition partners in government are failing New Malaysia. Fittingly in this constituency by the water, the political tide turned.

The decline in turnout among Malays was nominal, at an estimated 3.8%. Malay political parties were able to mobilise voters more effectively to come to the polls. Chinese and other non-Malay voters opted to stay at home as...
