Democrats are assured of maintaining their majority in the Iowa Senate, with one race headed for a recount and another to be decided in a December 11 special election.

Candidates for the Iowa legislature were required to submit campaign finance disclosure reports on October 19 and November 2. The Schedule E forms on “In-Kind Contributions” contained the most interesting numbers, because they showed how Democratic and Republican party leaders are allocating resources across the battleground districts.

After the jump I’ve enclosed in-kind contribution figures for the Senate districts expected to be in play tomorrow. Candidates running in other Senate races did not report large in-kind contributions from their respective parties.

Many candidates for the Iowa House and Senate tout endorsements by outside groups in their campaign communications. Some of those groups pay for direct mail, phone calls, or even advertising supporting their endorsed candidates.

Iowa’s influential political action committees and advocacy groups have very different ways of getting involved in the state legislative campaign. Follow me after the jump for examples of four distinct strategies.

In a surprising turn of events, Republican challengers are putting an obscure vote on water bottles at the center of their attacks on Iowa Senate Democrats. Follow me after the jump for background on this year’s equivalent to the non-existent “heated sidewalks” of 2010.

MARCH 16 UPDATE: Republican Elliott Henderson of Independence qualified for the ballot on the last day of the filing period. Bleeding Heartland will discuss his campaign in a future post.

State Senator Brian Schoenjahn confirmed today that he is running for re-election in the new Senate district 32. This politically balanced seat is a must-win for Democrats hoping to retain their majority in the upper chamber. With barely a month to go before the filing deadline for state legislative candidates, Republicans do not yet have a challenger in this district.
