Not all conservative politicians are clowns. Most likely the majority of them are hardworking, dedicated public servants.
But that is not 'showing leadership' for the people who fund Conservatives.
And in the #UCP / #CPC, funders appear to make all the decisions, not the membership. If they want a circus, then the public face will be clowns.
But that says nothing about the actual decision makers. They are deadly serious. What you see is the reflection of smoke in a mirror.
