At least 200 people gathered on the west steps of the Iowa State Capitol Monday evening for a rally and vigil marking one month since Trayvon Martin’s killing in Floriday. After the jump I’ve posted a few notes from the event, along with links about the impact of Martin’s death on the debate over proposed “stand your ground” legislation in Iowa.

Most bills that lack bipartisan support in the U.S. Senate die by filibuster, but senators voted overwhelmingly yesterday to move forward with debate on a bill that would end tax breaks for oil companies.  

Friday marked the second anniversary of President Barack Obama signing the Patient Protection and Affordable Care Act, more commonly known as health care reform or “Obamacare.” After the jump I enclose lots of news related to the milestone, including comments from Iowa elected officials and statistics on how certain provisions affect Iowans.

This morning the U.S. Supreme Court is scheduled to start hearing oral arguments regarding the constitutionality of the health care reform law. Governor Terry Branstad signed Iowa on to one of the lawsuits challenging the Affordable Care Act last year. Near the end of this post I’ve included some speculation about how the justices may rule (or punt).

What’s on your mind this weekend, Bleeding Heartland readers? Hope you are enjoying the unseasonably warm spring weather.

Mitt Romney may be the least-liked presidential front-runner ever among the Republican base, but he seems to have a lock on the GOP nomination. Despite losing the Louisiana primary convincingly to Rick Santorum yesterday, Romney has nearly half of the 1,144 delegates needed to secure the nomination. Santorum has fewer than half as many delegates, and only 21 states plus Washington, DC have yet to vote.

Someone has challenged the nominating petitions filed by State Senator Joe Seng, who is running against Representative Dave Loebsack in the second Congressional district primary.

Details are after the jump, along with the first e-mail blast from Loebsack’s campaign that discussed the primary challenge.

Yesterday the U.S. Senate approved an amended version of the Jumpstart Our Business Startups (JOBS) Act, which is supposed to make it easier for entrepreneurs to start small companies. All five Iowans in the U.S. House voted for this bill two weeks ago, but Iowa’s senators split on party lines.  

Republican rivals Rod Blum and Ben Lange continue to make very different cases for their candidacies in Iowa’s first Congressional district. Blum emphasizes his biography and experience, while Lange emphasizes the network of support he is building in his second attempt to defeat Representative Bruce Braley.

Follow me after the jump for a closer look at Blum’s pitch to Republican audiences and Lange’s new endorsements from nine GOP state legislators, complementing the steering committee he announced earlier this month.  

Polk County has long been dominated by safe Democratic Iowa House seats in the city of Des Moines and safe Republican seats in the suburbs. One of the few truly competitive recent Iowa House races in this county took place in 2008, when Republican Chris Hagenow defeated Windsor Heights Mayor Jerry Sullivan by fewer than 100 votes in what was then House district 59.

Hagenow was easily re-elected in 2010. For a long time I heard nothing about anyone stepping up to challenge him in the new House district 43, where I live. Earlier this month, Susan Judkins declared her candidacy here. Background on both candidates is after the jump, along with a map and details on the district’s political makeup.

The warm March weather has brought out many plants earlier than usual this year, which inspired me to launch a new series at Bleeding Heartland. Every Wednesday I will post at least one photo of a native wildflower blooming somewhere in central Iowa.

Today’s installment: bloodroot, which you can find in some wooded areas in March or April.

Consider this an open thread; all topics welcome.

When Iowa House Appropriations Committee Chair Scott Raecker announced plans to retire from the legislature after this year’s session, he created an opening for Democrats in what would have otherwise been a hopeless district. Follow me after the jump for background on the new House district 40 and the two men who will compete to succeed Raecker.

The redistricting process and several Republican retirements have created many pickup opportunities for Iowa House Democrats. The devastating 2010 election left them nowhere to go but up in the lower chamber, where Republicans currently enjoy a 60 to 40 majority. Relatively few sitting House Democrats represent vulnerable districts.

Speaking to activists at the Polk County Democratic convention on March 10, I heard lots of optimism about the House races. After the jump I’ve posted some early thoughts on the seats up for grabs.

In a step forward for small-scale wind power in Iowa, the Iowa Utilities Board designated Johnson County and Floyd County as our state’s first Small Wind Innovation Zones last week.

The Iowa legislature’s second “funnel” deadline passed on Friday, which means that most non-appropriations bills are dead unless they have been approved in one chamber and in at least one committee in the other chamber. It’s time to catch up on the most significant bills being debated in the Iowa House and Senate.

I’m posting the weekend thread early, because the filing period for primary election candidates in Iowa closed this afternoon. The Secretary of State’s Office posted the full list of candidates here (pdf). John Deeth has been covering the filing on a daily basis all month at his blog. Some highlights from races I’m watching are after the jump.

This is an open thread; all topics welcome.

UPDATE: Gotta agree with Senator Chuck Grassley: the History Channel is useless.

The Iowa Supreme Court ruled unanimously today that Governor Terry Branstad impermissibly used his line-item veto to strike language about Iowa Workforce Development field offices without vetoing the money allocated to fund those offices.

UPDATE: Added Branstad’s reaction below as well as statements from Iowa House and Senate Democrats.

The U.S. Senate approved a new transportation authorization bill on March 14. Iowa’s senators Chuck Grassley and Tom Harkin were both part of the 74 to 22 majority supporting the highway bill, officially called MAP-21. Republicans cast all of the no votes. In today’s polarized Senate, 74 votes looks like an overwhelming mandate, but it’s worth noting that even larger bipartisan majorities approved the four previous transportation authorization bills from 1987, 1991, 1998, and 2005.

Before final passage of MAP-21, senators voted on numerous amendments. Some were related to transportation policy, while other “non-germane” proposals were considered as part of a deal to avoid a Republican filibuster. Bleeding Heartland covered how Grassley and Harkin voted on the first batch of amendments here. Follow me after the jump for details on the rest of the Senate debate over the transportation bill. Iowa’s senators were on opposite sides most of the time.

All the expected Congressional candidates in Iowa have filed nominating papers with the Secretary of State’s Office: Bruce Braley, Ben Lange, and Rod Blum in the first district; Dave Loebsack, Dan Dolan, and John Archer in the second district; Leonard Boswell and Tom Latham in the third district; and Steve King and Christie Vilsack in the fourth district.

No one I talked to last weekend saw petitions for State Senator Joe Seng at various county conventions in IA-02. Therefore, I assume Seng will not file to challenge Loebsack in the primary. Either Iowa’s worst Democratic lawmaker was just looking for a little free publicity earlier this month, or he didn’t realize how many signatures he would need to qualify for the ballot as a Congressional candidate. FRIDAY UPDATE: I was dead wrong–don’t know how Seng got the signatures, but he’s on the candidate list from the Secretary of State’s Office.

To mark the field being set in all four districts, I’m posting updated active voter registration numbers for Democrats, Republicans, and no-party voters in all 99 Iowa counties, grouped by Congressional district. The numbers in the tables after the jump come from this page at the Iowa Secretary of State’s website (pdf).

Any comments about the Congressional races are welcome in this thread. I love this story about Dolan accidentally addressing the wrong convention in Monroe County last Saturday. The Democratic delegates politely listened to his stump speech, after which someone raised his hand to suggest Dolan might want the Republican convention instead. Now that’s what I call Iowa nice!

UPDATE: Here’s a change of pace: King has never debated a Congressional challenger before, but he is proposing to debate Vilsack six times. No word yet on the details of the offer.

A third Democratic candidate has filed nominating papers in the new Iowa Senate district 38. Nick Volk, a bank vice president from Walford (Benton County), will face LaForest Sherman and Shelley Parbs in the June primary. The winner will take on first-term Republican State Senator Tim Kapucian in a swing district. A map is after the jump, along with more background on Volk.

U.S. Attorney Stephanie Rose told members of the U.S. Senate Judiciary Committee yesterday that she wasn’t a key decision maker regarding the May 2008 immigration raid in Postville, Iowa.

Following up on this post: Des Moines Register Editor Rick Green has announced that the newspaper will publish all of this week’s Doonesbury comic strips in the Sunday Register Opinion section. The paper will also run commentary for and against the Texas ultrasound law, the target of Garry Trudeau’s ridicule.
