Every year we hear how polls show congress has a very low approval rating.
The latest is supposedly 9% - below cockroaches and hair lice.
Yet every election we see something approaching 90% of incumbents reelected.
See: "Reelection Rates Over the Years"
These are not mutually exclusive possibilities.
The reelection rate is not a problem of the lack of term limits. The problem is the government and thus incumbents have WAY to much power and influence over our lives. The offices carry with it unlimited income potential and celebrity status.
Take away the power of government and the perks that go with elected office, the way the founders intended, and the incumbents will term limit themselves.
The answer is to limit GOVERNMENT not the terms of office.
