Iowa House and Senate candidates were required to file their last pre-election campaign finance reports on Friday. In stark contrast to four years ago, Republicans are outspending Democrats in most of the contested state Senate districts. (I’ll address spending in the key Iowa House races in a different post.)

Currently, there are 25 Senate Democrats, 23 Republicans, and one independent. If former GOP Senator David Johnson makes good on his promise to remain an independent in 2017, and Democrats win the December special election to replace the late Senator Joe Seng, Republicans would need to pick up three seats to gain control of the upper chamber for the first time since 2004.

I enclose below in-kind contribution figures for the Senate districts expected to be in play next Tuesday. Candidates running elsewhere did not report large in-kind contributions from their respective parties.

No Iowa Democrat has frustrated Republicans more over the last six years than Senate Majority Leader Mike Gronstal. The 26 to 24 Democratic majority in the state Senate has kept dozens of bills on the conservative wish list from reaching Governor Terry Branstad’s desk. After a net gain of six Iowa Senate seats in the 2010 wave election, many Republicans were confident that gaining control of the upper chamber was only a matter of time. However, Democrats managed to keep that one-seat majority despite a new map of political boundaries that gave Republicans lots of opportunities in 2012. Another GOP landslide in 2014 failed to deliver any net gain for the party in the Iowa Senate.

I’ve long believed Gronstal was well-positioned to win re-election again. Earlier this year, the Iowa Firearms Coalition PAC made the same calculation, leaving Gronstal’s district off its list of targeted Iowa Senate races.

But even if Senate district 8 isn’t among the most promising GOP pickup opportunities, Republican leaders will invest resources in this race, especially since their preferred challenger, Dan Dawson, won a three-way GOP primary. A television commercial introducing Dawson to voters is already in the can.

Follow me after the jump for a closer look at Senate district 8, its recent voting history, the two candidates, and likely themes of the general election.

The Iowa Firearms Coalition, an affiliate of the National Rifle Association, has formed a political action committee that is targeting four Democratic-held Iowa Senate districts in its effort to strip power from “anti-gun Senate majority leaders.” The strategy is logical, because in recent years several high-profile gun bills died in the upper chamber after clearing the Republican-controlled Iowa House.

However, I was surprised to see a couple of Senate races missing from the Iowa Firearms Coalition PAC’s list.
