It’s been a while since Bleeding Heartland posted a thread dedicated to the Iowa Senate races. Democrats go into the election with a 26 to 24 majority in the upper chamber, where 25 of the 50 districts are on the ballot this year. Only a handful of those races appear to be competitive.

Carolyn Fiddler, who blogs about state legislative races here, has rated the Iowa Senate as a “Tossup/Tilt D” chamber on her list of state legislative chambers most likely to flip. In those terms, I consider the Iowa Senate a “lean D” chamber, as a lot has to break for Republicans to get them to 26 seats.

In theory, Democrats are defending six seats: five incumbents have challengers, and one Democratic-held seat is open. In reality, Republicans have failed to mount strong challengers against Amanda Ragan in Senate district 27 or Tod Bowman in Senate district 29. Moreover, the Iowa GOP is not putting significant money behind Jeremy Davis, its challenger in Senate district 23. Davis has just started running some positive radio ads in the Des Moines area, whereas radio commercials were launched more than a month ago in the targeted races.

The Democratic incumbent who appears to be most at risk is Daryl Beall in Senate district 5. His territory changed quite a bit with redistricting, and Mitt Romney carried it in the 2012 presidential election. Republicans are also making a strong play for the open Senate district 15. Both parties have been running radio ads since late September, but as of last week only Democrats were on television in Senate district 15, with a positive spot about Chaz Allen. To a lesser extent, Republicans have put money behind Brian Schmidt’s campaign in Senate district 49, but the demographics of that district favor incumbent Senator Rita Hart.

Republicans could win two of the Democratic-held Iowa Senate seats, but that won’t get them to the magic 26 unless they hold all of their current seats. Two of those are heavily targeted. In the open Senate district 39, both parties have been advertising on the radio for more than a month. Democrats have invested far more in television ads (all positive for Kevin Kinney) than Republicans have for Mike Moore.

The other Republican-held Senate seat most at risk appears to be Senate district 41. By voter registration and top of the ticket performance, this should be a Democratic seat. The best thing going for State Senator Mark Chelgren is that Mariannette Miller-Meeks is the Republican nominee in Iowa’s second Congressional district. She’s an underdog against Representative Dave Loebsack, but a strong turnout for her in the Ottumwa area would benefit Chelgren, as it did in 2010.

Carolyn Fiddler encouraged readers to keep an eye on Senate district 47, but even though Barack Obama carried that district in 2012, it would be an upset for Maria Bribriesco to defeat incumbent Roby Smith. That said, Democrats have hit SD-47 with quite a bit of direct mail.

Any relevant comments are welcome in this thread.

UPDATE: Forgot to mention that surrogates have gotten involved with many of these races. Senator Tom Harkin headlined an October 27 rally in Fort Dodge for Beall. Maryland Governor Martin O’Malley did an event earlier this month for Steve Siegel in Senate district 41. On the Republican side, Governor Terry Branstad has been in Ottumwa recently to help Chelgren and plans events for the GOP candidates in Senate districts 15 and 39 soon.

SECOND UPDATE: Tim Kraayenbrink, the GOP challenger to Beall in Senate district 5, has just started running a positive television commercial in the Des Moines market. The gist is that he’s a small business owner, unlike “career politicians in Des Moines.” I haven’t caught it on tape yet but am fairly certain he did not mention Beall by name.

Radio commercials appeared in several competitive Iowa Senate districts during the last week of September, coinciding with the start of early voting. This week, the Republican Party of Iowa has launched the first negative radio spots I’ve heard in state legislative races this year. After the jump I’ve enclosed the transcript of the ad attacking Chaz Allen, the Democratic candidate in the open Iowa Senate district 15. Allen’s own positive ad, which Bleeding Heartland transcribed here, is still in rotation and promotes the former Newton mayor’s record of recruiting businesses. The new Republican spot blames Allen for high property taxes that allegedly discouraged companies from coming to Newtown after “Maytag pulled out on Chaz Allen’s watch.” The ad also plays up Governor Terry Branstad’s support for Crystal Bruntz, the Republican candidate in Senate district 15. While the ad asserts that Bruntz “understands job creation,” it fails to mention anything substantive she has ever done to create jobs.

In Iowa Senate district 41, a leading pickup opportunity for Democrats, Republican State Senator Mark Chelgren’s new radio spot highlights flippant and sarcastic responses Siegel mailed in response to a survey Chelgren circulated in 2010. More details on that commercial are after the jump.

In the open Senate district 39, another seat targeted by both parties, a Bleeding Heartland reader tells me that the new Republican radio spot attacks Democratic nominee Kevin Kinney over his support for “Common Core” educational standards. I have not heard the ad yet and would appreciate any further details. It seems like an odd angle for an attack, but I guess Kinney’s background as a deputy sheriff and family farmer didn’t give them easy targets. Politics-watchers generally believe that education is a campaign issue favoring Democrats. As far as I can tell, fear-mongering over Common Core only resonates with social conservatives who would already be voting for Kinney’s opponent, Michael Moore.

I have not yet heard details on radio spots attacking State Senators Daryl Beall or Rita Hart, the Democratic incumbents in Senate districts 5 and 49, respectively. Nor have I heard of any attack ads against three-term Democratic incumbent Amanda Ragan in Senate district 27, although anecdotally, Republicans have supposedly given up on taking back that seat. I always appreciate tips from Bleeding Heartland readers, so please let me know if you’ve heard radio ads in the Fort Dodge, Clinton, or Mason City area.

In the open Iowa House district 55 (northeast Iowa), Republican Daniel Branhagen started running a commercial this week calling his Democratic opponent Rick Edwards a big spender. I haven’t heard attack ads against any Iowa House Democrats yet on Des Moines area radio stations.

Any comments about the state legislative races are welcome in this thread.

The filing period for general-election candidates closed on August 15. You can view the full candidate list for federal and state offices on the Iowa Secretary of State’s website. John Deeth briefly reviews all 100 House races here. Next month, I’ll be posting on the most competitive Iowa House races.

For today, I’m interested in what appears to be a pattern of Republicans letting Iowa House seats go in battleground Iowa Senate districts. I suspect a strategy is in play to depress GOTV in the more Democratic halves of these districts.
