It's very possible to be a clean or a good politician as you may term it but the problem we have is that after supporting some new politicians who promise to be different, they will end up joining the already existing bad politicians in their bad leadership. Here in my country we have had a few individuals who joined politics and the masses trusted them so much and ensured that they emerge victorious during election, but what we got in return was absolute betrayal because these set of new politicians got spoilt and influenced by the bad politicians.

Nevertheless, if you really wish to serve your people with honesty, you can still achieve it by maintaining sanity, integrity, and human sympathy.
