You need to watch the discussions around "entitlement reforms" that's being promoted currently. Voters can't reject candidates after the fact, who won't seek re-election after passing (or being the lightning-rod of) unpopular legislation, opting instead for cushy "jobs" in the industry they legislated in favor of against their consituents interests.
