Technically, the plan didn't limit their terms. When the U.S. Supreme Court struck down congressional term limits, critics filed a lawsuit seeking to overturn the state restrictions also. If critics really think the voters didn't want to restrict the terms of state officeholders when they voted to do exactly that, they can circulate petitions for a referendum repealing term limits. Besides, term limits are working well where they have been tried. There are 14 new members on Jacksonville's 19-person City Council, for example, and the new group is functioning smoothly, so far.
Fresh ideas are always useful.
Critics say public bodies will lose a lot of good people. But the voters are willing to risk that, as a tradeoff for getting rid of the entrenched bad ones. Politicians of any stripe tend to think they are indispensable. If a displaced politician really is talented, he can always stand for another office, where his talents may do even more good. Some also say lobbyists will have too much influence with inexperienced legislators.
