Dog whistles in Houston political campaigns - What's Your Point?

HOUSTON (FOX 26) - This week's panel: Wayne Dolcefino, media consultant;  Charles Blain, Urban Reform; Carmen Roe, legal analyst and Houston attorney; Antonio Diaz-, writer, educator and radio host; Michelle Maples, conservative attorney; Anthony Graves, criminal justice advocate; join Greg Groogan to talk about the latest in Houston politics. 

A week agon on What's Your Point, we discussed claims by Mayor Sylvester Turner's campaign that the incumbent was being targeted by racial attacks from political opponents.

Tuesday, that narrative continued as the mayor described allegations of corrupt "pay-to-play" practices as nothing more than a dog whistle, aimed at inciting those with preconceived notions about African- American office holders. 

Then a tweet from the mayor's press secretary aimed at Houston firefighters "So if the fire union won a vote to. let's say reinstate slavery and the city went to court to have it declared unconstitutional, would you be mad? Because that is how the system works, when the law is at odds with a referendum."

Critics, and there were many, were outraged at Mary Benton's attempt to inject the abhorrent concept of slavery into a debate over Proposition B. Was Benton's analogy legitimate or the kind of calculated "dog whistle" the mayor has condemned?
