One final observation about Saturday's Dallas City Council runoff election

The chances of defeating an incumbent Dallas City Council member seeking re-election are just about zero. If Carolyn Davis can't be beaten, no one can. The chances of defeating a term-limited council person's designated successor are slim -- witness the two newly elected city council members: Ann Margolin, Mitchell Ransansky's choice to replace him, and Delia Jasso, Dr. Elba Garcia's choice to succeed her -- but not as small as defeating an incumbent. If Carolyn Davis accomplishes one thing as a member of the city council -- and if her record is any indication, it may be only one thing - -it's that potential city council candidates should not waste their time, their money or their energy running against an incumbent.
