If politicians became politicians for such lofty goals, then why do problems like vested interests always persist in government (especially the US)?
Where does someone like Nelson Mandella fit within the framework of your reasoning?
It is difficult to answer your question because the answers are many, and complex.
So I will condense it down to this, the premise of your question suggests that politicians are somehow fundamentally different from you, me, joe schmo on the street corner. There is no difference. They're persuadable, corruptible, egotistical, can get angry, can be misled, can be happy, can be inspirational, can be you or me.
If there is a problem, the problem isn't with the people, it is with the system. There is massive structural failings. It has bit by bit, intentionally or accidentally, evolved into a monster that incentivizes the actors to play by the monsters rules.
Which is mostly why I am largely sceptical about the "tea party". It is simply more meat for the monster.
If you have inflexible principles that conflict with the monsters interests you will be marginalized and/or removed.
TGD and MPJH posts help explain one small facet of the complexity. At the local level politicians will spend more time with joe schmo, while at the state or national level, politicians will spend more time with Jeremia Alexander Blueth the 3rd, CEO of Corruptocorporation. It is easier to persuade someone to advance a position that aids you, when you have access to the person you need to persuade.
