Michael Cass's article did make me aware that John Summers started a Neighborhood PAC called Nashville Neighborhood Defense Fund to "recruit and to support pro-neighborhood candidates for local and state offices." I had received a mailer from them some time ago, and I was sort of waiting to find out more information before deciding whether to lend my support.
I have now decided. I threw the mailer away. Helping neighborhoods generate more power in government is a worthy cause, but its street cred is hurt by the ambitions of this particular founder.
