The entirety of politics, 2 terms lifetime, social security, and obumercare. Anything else invites corruption. Also while acting as a candidate, it needs to be illegal to even mention their opposition and or party affiliation. A candidate need only sell him/her self and their ideas/agenda. Candidacy should be revoked for any violation, immediately.
Also, maximum age limits must be set. No older than 60 by election day, making 68 by end of 2 terms.
Taking away benefits/perks from these entitled abusers of the system will result in less career minded individuals resulting in more individuals who want to make a difference.
No more old bodies taking up space so they can be told when to raise their hand.
