Current partisan balance of the Iowa Senate.  This map should be updated, but old versions should be split off into separate files so that there is a file for each General Assembly.
File:Iowa State Senate election results blank, 2002-2012.svg with partisan data from en:Template:Iowa State Senators.  The file was created from https://www.legis.iowa.gov/Resources/Redist/redistricting.aspx?planYear=2001 (specifically the "senate.shp" file in https://www.legis.iowa.gov/DOCS/Resources/Redist/2001/plan2shapefiles.zip) and was converted with http://indiemapper.com/app/.
