The Daily Kos Elections team has been compiling 2012 presidential election results by state legislative district as well as by Congressional district. Yesterday the Iowa numbers were added to the database. You can view Google documents with raw vote totals and percentages for Barack Obama and Mitt Romney by Iowa Congressional district here, by Iowa Senate district here, and by Iowa House district here.

Looking closely at the presidential vote in the legislative districts provides some insight about where the competitive Iowa statehouse races might be next year. After the jump I’ve highlighted some key data points related to the Iowa Senate races. Later I will post a separate diary with first thoughts about the Iowa House districts.
