I wonder if it would be better to have a term limit. I don't really care if you are 125, but there should be a limit to how long you sit there with huge amounts of power. Especially since they aren't directly re-elected.
No. For two reasons, one you don't want to force the people to give up an actually good representative. Two, term limits for Representatives and Senators actually creates more corruption and entrenches the party as the entity instead of the politician.
