While I see the attraction to term limits, I think there’s some simple solutions;
All campaign funds not spent during an election (or to pay off debts incurred during the election) revert immediately to the government. (No more war chests.)
All laws equally apply to all citizens, elected officials and public employees. If one is granted an exception, it is immediately granted to all. (Cops don’t have background checks? Neither does anyone else. Politicians exempted from health care? Same with the people. Etc.)
Embezzlement of public funds, selling votes, cash for influence, etc which are already crimes shall be punished by no less than complete seizure of all assets the defendant had access to in the past 5 years and imprisonment for no less than 10 years. (Get caught, lose everything.)
How does that (I respectfully ask) rid us of lobbyist butt kissing career politicos. In my humble opinion this is amongst our major problems. Two terms and out! Join the ranks of the rest of us in the salt mines.
