The 2010 Iowa State Senate elections took place as part of the biennial 2010 United States elections. Iowa voters elected state senators in half of the state senate's districts—the 25 odd-numbered state senate districts. State senators serve four-year terms in the Iowa State Senate, with half of the seats up for election each cycle.
The primary election on June 8, 2010, determined which candidates appeared on the November 2, 2010 general election ballot. Primary election results can be obtained here.
Following the previous 2008 Iowa Senate election, Democrats maintained control of the Iowa state Senate with 32 seats.
To reclaim control of the chamber from Democrats, the Republicans needed to net 8 Senate seats.
Democrats maintained control of the Iowa State Senate following the 2010 general election; however, their majority was significantly reduced from 32 to 26 seats. Republicans saw their numbers soar from 18 to 24 seats.
