Senior senators and and reps. are not afraid of being voted out. They are chairmen and ranking members in various committees. They are able to bring benefits to their states. So people in their state place them to the seat again and again. They have much advantage over their challengers.

These people are kings and emperors. They don't care about what the public opinions are, but do whatever they like. Even their proposals are defeated again and again, they keep staging new unpopular bills, as Kennedy did.

A term limit for congress members is necessary, to expel these bad eggs and fill the chambers with fresh members who better understand American people's desire and need.
