I suggest taking a few minutes to watch Henry Cisneros views on the election. Yes, the Chick-fil-A thing hurt the incumbent, but it sounds like it was more self inflicted damage where he has a continuous problem of not laying out explanations for his actions but just overarching themes. He couldn't Hammer home the point that had nothing to do with religious values but rather just at Chick-fil-A was closed on Sunday which is a prime travel day , making it a bad fit for the airport.
It sounds like an even bigger issue was that he's had conflict with the firefighters Union which backed his opponent big time. So ironically the trumpist guy was ready to a blank check to the union if he got elected.
