He had baggage before joining the CPC but sealed his fate with the long form census fiasco.
He could've told the PMO it won't work,that the chief statistician was against it, the data would suffer etc., instead Clement said he and the head of Stats Can thought it was a great idea!

A yes man doing as was told like an obedient soldier, which is great, but doesn't make you a leader.
