The founding Fathers did not intend for citizens to make serving the country as legislators a career. Although some of them were, I suspect, career politicians, the aim was for citizen legislators to run the country and the local governing institutions. To get rid of the career politicians, some citizens in some state and local areas have passed laws limiting the terms of mayors, county commissioners, city council persons, and other elective positions.
The best form of term limitation is for voters to kick the incumbents out. Whenever a politician has served for decades in the US Congress and then during one election, he or she tries to run against those rascals in Washington, it is time to vote that politician out of office.
The same goes for those who change parties to remain in office. When a politician changes parties, you know he or she has no principles. The one thing they value is remaining in office. Politics for them is not just a career, it is a way of life.
So, the insurrection against incumbents of both parties is good for the country, isn’t it?
