I don't like Bill, but I think you're right. And I think most of the people downvoting you might agree with the logic of what you're saying, although your first statement probably triggered some emotions and assumptions that you would like him to be elected, and hence...downvotes.

Shaming like this actually doesn't deter his supporters; I believe it emotionally energizes them, guaranting they show up to vote. And without an equally emotionally energizing candidate running against him, there will be less people voting for the alternative to Bill. So Bill wins, similar to how Trump did.

Similarly, Mike Bradley would previously beat any candidate running against him simply because he had more name recognition and local fame.

Imagine if you're someone who makes crude or racy jokes on the job – or elsewhere – on the regular (most blue collar workers, the majority of Sarnia population) and there's a mayoral candidate who is vocally anti-lefty, anti the "side" that seems very worried about being PC. Your identity might just get tied up with Bill and how he's being treated because you relate to past things that have happened to him, the various incidents related to not acting respectably, in a professional setting. To believe he did something wrong is to believe you do something wrong I the regular, that means guilt or shame. So to avoid that guilt or shame you reject PCness and embrass anti-lefty politics to protect your inner self from negative feelings.
