Mahathir want Samy to quit

Former prime minister Dr Mahathir Mohamad thinks that MIC president S. Samy Vellu should quit his post altogether "if he knows what's good for him".The only reason he gave is that he is no longer in government and neither are the others who were once with him. Why is Mahathir picking on Samy, when we have the equally glaring case of Rajah Abdul Taib Mahmud in Sarawak? Like Samy, he refuses to go away as well and continues to hang to power. Taib became Sarawak chief minister even before Mahathir became prime minister in early 1981.
So Mamak Mahathir why dah, you see no reason to call Taib to quit but only Samy. Is it because of he is am Indian? Dai Samy, the mamak is attacking you dah? What u going to do? Nothing I suppose, 52 years no do anything? Aiyo..karavaleh!
