This is an impressive frontal assault by the Flames owners to unseat Nenshi in the upcoming election and adds to the already increasing concerns the voters have with him.

With the unprecedented rise in property and utility taxes since he has been in office, Nenshi has shown little fiscal restraint in very challenging economic times. 

In addition, his drive to higher densities, to increase the tax base and revenues, have negatively affected established property values in the parts of the city which has further angered the voters. 

Calgary city council has had the most closed meetings of any municipality in Canada - something new during his tenure - so Calgarians not only participate less in decisions they are given no rationale for them. 

I am not even sure if Nenshi makes a deal with the owners he will stave off the negative wave that is building against him.
