Political Scene in Malaysia

We had the Bersih 3.0 recently which aim to clean up the "DIRTY" election board... but will we get a "clean" government when we change the current government? Corruption will be there no matter where you go... will ANWAR's government act 100% for citizen's wellfare?? the transformation of the government will benefit US?? Will it make all the politician to be more GREEDY during their service?? they might try to be more "CORRUPT" to gain more during their short service term. Try to think about it...
