Term limits should be placed on all elected positions throughout the entire country. No person should hold elected political office more than 2 terms. This should apply for every level from local to federal. This would reduce government corruption, ensure people don’t make a career out of any single position, and encourage more people to enter politics.
Why restrict those of good governance ? If you want dirty politicians removed then get the Oath of Office enforced at ALL levels of government, that would create ‘turn over’ while showing that the US is a Republic under the laws.
