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.
