The 2020 Iowa State Senate elections took place as part of the biennial2020 United States state legislative elections. Iowa voters elected state senators in half of the state senate's districts – the 25 even-numbered state senate districts. State senators serve four-year terms in the Iowa Senate, with half of the seats up for election each cycle.
A statewide map of the 50 state Senate districts in the 2020 elections is provided by the Iowa General Assemblyhere.
The primary election on June 2, 2020, determined which candidates appeared on the November 3 general election ballot. The filing deadline was March 13.[1][2]
Following the previous election in 2018, Republicans retained control of the Iowa Senate with 32 seats to Democrats' 18 seats. To reclaim control of the chamber from Republicans, the Democrats needed to net eight Senate seats.
Republicans retained control of the Iowa Senate following the 2020 general election, with the balance of power remaining unchanged.
Reminder: Only even-numbered Iowa Senate seats were up for election in 2020; therefore, odd-numbered seats were not having elections in 2020 & are not shown.
Note: If a district does not list a primary, then that district did not having a competitive primary (i.e., there may have only been one candidate file for that district).[6]
