The 2004 Iowa State Senate elections took place as part of the biennial 2004 United States 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 State Senate, with half of the seats up for election each cycle.
The primary election on June 8, 2004, determined which candidates appeared on the November 2, 2004 general election ballot. Primary election results can be obtained here. General election results can be obtained here.
On election day in November 2004, Republicans had control of the Iowa state Senate with 29 seats.
To take control of the chamber from Republicans, the Democrats needed to net 5 Senate seats.
The result of the 2004 election was an evenly-divided Iowa state Senate with Democrats netting 4 flips and the resulting balance being 25 seats held both by Democrats and Republicans. As a result, Jeff Lamberti and Jack Kibbie were deemed co-Senate Presidents for the Republican & Democratic halves, respectively.
Summary of Results
NOTE: Only even-numbered Iowa Senate seats were up for regularly-scheduled election in 2004.
