It was sarcasm. Assuming no crossover (which is a very bad assumption, but one I am going with for this example), you have 2,537 people in Washington in this list that are movers and shakers who would never be affected by term limits.
Congressional staffers, lifetime bureaucrats, and lobbyists count in the tens of thousands of people who run Washington.
Preventing only 535 positions to be “term limited”, while allowing the tens of thousands of unelected positions to stay that the status quo does nothing to change Washington or the results we get from Washington.
That is why term limits are useless and in many ways counterproductive.
I agree with you, term-limits wouldn’t be a solution and could make things worse. I can’t think of any better solution than an informed and far less gullible electorate. It is like these Congressman are political crack cocaine and the electorate can’t overcome the addiction. If they are rotten, don’t vote for them again.
