California instituted term limits for its state representatives in 1990. It seemed like a good idea at the time, but what you end up with is that the most senior politicians in Sacramento are the lobbyists.

The outcome of that is that most bills are written by lobbyists and most state reps vote how the lobbyists tell them to, because they lobbyists are the ones making the deals with the other lobbyists, instead of the long time representatives being in leadership.

Each system has its pros and cons, but one of the main cons of term limits is that lobbyists are in control.
