Correlation != Causation does not apply when the system is under the control of single entity. So many of these governments have been run by the same party for decades on end. If these long-term rulers didn't cause the bad outcomes from the time of their reign that only means they were completely ineffective. Why should ineffective government be kept around? It is plain stupid to not hold elected leaders responsible for actual outcomes produced under their watch.
