A local academic sends an e-mail reminding me that aldermanic demogaguery in Milwaukee was certainly not limited to the McGees. Some of us remember Bob Anderson, a south side alderman, whose singular contribution (besides constituent service)was to rile people that his constituents didn't like. Other than that the city was no better for his 32 years on the council and I suspect that the McGee legacy will be just as rich.
My correspondent (who I do not have permission to name)also remarks upon the similarity betwwen McGee and segregationist politicians like George Wallace and Pitchfork Ben Tillman, a connection that had occurred to me. The point is not that all are racist, but that they prosper by convincing voters that antagonizing the "right" people is tantamount to accomplishment.
There are lawyers who prosper in the same way. They impress clients by being ineffectually beligerent.
