I don't really have any details on this other than Art is announcing today that he won't run for re-election. I'll update once I get more details.
The press conference has recently been concluded. Art Hanger, 64, has been the MP for Calgary NE since 1993. First elected as a Reform, then a Canadian Alliance, and finally as a CPC member in the 2004 election. No specific reason has been given, but after 14 years as an MP I can understand why he'd want a rest.
Art has served his constituents well over these past 14 years. As an ex cop I think he brought a perspective to the Parliament regarding crime and justice issues that really hadn't been represented before by the multitude of lawyers who became MPs.
