Presidential aspirants prime movers of impunity

It would be harsh to judge Members of Parliament who may have hit the peak of their ambitions on similar terms as presidential aspirants.

A legislator, who was once a youth winger for another mheshimiwa may have no more mountains to climb. For those who may have reached the  height of their aspirations, the integrity bar may be lowered.
Such MPs may be excused even during the age of the new Constitution because they do not have ambitions for president.
If they entertain such illusions, then they have not declared them. When they do, the integrity bar shall be raised. For now their credibility threshold is lower.
