The C&R QGIS Redistricting Plugin is almost available!
Creating political districts has always been an expensive proposition for users wanting to leverage the power of a GIS software package. The C&R Redistricting Plugin allows you to draw and update political districts or sales turf from directly within QGIS.
The plugin currently works with QGIS version 2 and can be downloaded through the official QGIS plugin repository. (Note: the plugin is currently going through the approval process and will be available for download shortly.)
A tutorial and manual for use is also available! Download here: C&R QGIS Redistricting Plugin Manual
