About a week ago on this blog I told you how Ann Margolin would be taking on Raj Narayanan in the race for Mitchell Rasansky’s seat on Council. Well, a lot can change in a week. There’s now a new contender for that vacancy: Brint Ryan, founder of Ryan (a leading US tax firm). Dallas Observer reports that Allyn & Company will manage his campaign. Ryan promises to focus on the spending (and mis-spending) of taxpayer’s money, like those flat screen TVs at City Hall.
