After analyzing video data from roughly 1,700 crashes, University of Iowa researchers determined that “distracted driving contributes to nearly 60 percent of car crashes involving teen drivers” between the ages of 16 and 19. That’s a far higher figure than previous studies have indicated. The findings are significant because although teenagers drive less than most other age groups, “their numbers of crashes and crash deaths are disproportionately high.”

The full report, “Using Naturalistic Driving Data to Assess the Prevalence of Environmental Factors and Driver Behaviors in Teen Driver Crashes,” is available here (pdf). Some highlights are here and after the jump, along with more details about the methodology.

Interacting with passengers in the car and talking or texting on a cell phone were among the most common distractions preceding teen driver crashes. Proposed legislation to ban most cell phone use while driving did not make it through the Iowa legislature’s “funnel” this year, so it’s up to parents to help address the problem by voluntarily not texting or carrying on phone conversations while they drive.

A bill prohibiting school districts from starting the academic year before August 23 is on its way to Governor Terry Branstad, who has indicated that he can accept the compromise. UPDATE: The governor signed the bill on April 10.

The school start date issue has taken up a lot of oxygen at the statehouse this legislative session, despite a lack of evidence that the timing of the academic year affects Iowa’s tourism sector in any meaningful way. Follow me after the jump for details on Senate File 227‘s journey through the legislature, including how Iowa House and Senate members voted on different versions of the bill.

The governor’s determination to use state power to supersede decisions reached independently by more than 300 school boards and superintendents is yet another example of the Branstad administration’s disregard for local control in many policy areas. For my money, that’s one of the most under-reported Iowa politics stories of the last five years.

Like the zombie lie that cannot be killed, social conservatives defending business owners who would decline services to gay couples continue to rely on the same analogy about the government hypothetically forcing a Jewish deli owner to handle and serve non-kosher food.

Bleeding Heartland has discussed the basic logical flaw here, but let’s walk it through one more time.  

Aside from Senator Ted Cruz kicking of his presidential campaign, last week was a relatively quiet one in Iowa caucus news. But there are still plenty of stories and prospects to discuss.

Any comments about the presidential race are welcome in this thread. Follow me after the jump for a news roundup.

A rare event happened on Thursday, as the U.S. House approved by a large bipartisan majority a bill changing a major entitlement program. Iowa Republicans Rod Blum (IA-01) and Steve King (IA-04) were among those who opposed the Medicare Access and CHIP Reauthorization Act of 2015.

All topics are welcome in this open thread. Representative Steve King (R, IA-04) inspired the unifying theme of this weekend’s post, when he approvingly linked to this recent article by Heather Mac Donald called “Practical Thoughts on Immigration.” King commented, “USA declining 2 Third World status bc shrinking %age who would reverse course don’t realize demographics r destiny.” At this writing, King has not responded to my request that he clarify whether he meant to say that a U.S. where non-Hispanic whites are a minority would inevitably sink to “Third World status.”

Meanwhile, the latest estimates from the U.S. Census Bureau indicate that immigration contributed greatly to Iowa’s population growth of 2 percent between 2010 and July 1, 2014.

After the jump I’ve enclosed a map showing the latest Iowa county population estimates, some links on the Census Bureau data, and excerpts from Mac Donald’s commentary, which struck a chord with King.

A leading political action committee for pro-choice Democratic women has endorsed Monica Vernon in Iowa’s first Congressional district. EMILY’s List announced their support today in a statement I’ve posted after the jump. The PAC didn’t endorse any of the three women who sought the IA-01 nomination in 2014, but donated $10,000 and bundled another $233,283 to Staci Appel’s campaign in IA-03.

Vernon finished second in the 2014 primary and is the front-runner for the Democratic nomination this cycle. However, she may not be the only pro-choice woman in this race. Former State Senator Swati Dandekar, who finished third in last year’s primary, is considering another Congressional bid.

Please share any comments about the IA-01 campaign in this thread.

Geri Huser may need to recuse herself from the Iowa Utilities Board’s upcoming decisions regarding the Bakken Pipeline proposal, according to a report by Ryan Foley for the Associated Press.

The U.S. House approved a draft budget yesterday with some drama along the way. Details on the important budget provisions and how the Iowans voted are after the jump.

All topics are welcome in this open thread. What news stories captured your attention lately?

Although Congress acted during the 1970s to ban employers from discriminating against pregnant women, both attorneys and women have told me over the years that pregnancy discrimination remains common in the workplace. The U.S. Supreme Court weighed in today in the case of Young v. United Parcel Service. I enclose below some links about this important ruling.

Former Maryland Governor Martin O’Malley continues to do everything a politician would do to set up a strong Iowa caucus campaign.

So why am I still having trouble believing he will offer himself to Democrats as a alternative to Hillary Clinton?  

Heather Matson announced today that she will run for Iowa House district 38 in 2016. To my knowledge, she is the first Democratic challenger to declare against an Iowa House incumbent.

The district should be competitive, and Matson and four-term State Representative Kevin Koester each bring strengths to the campaign. After the jump I’ve enclosed a district map, recent election results and voter registration data, and background on both candidates.

U.S. Senator Ted Cruz of Texas officially launched his presidential campaign this morning. Click here to watch his speech at Jerry Falwell’s Liberty University or here to read the transcript.

As an outsider candidate, Cruz will need a strong showing in the Iowa caucuses to have any hope of becoming the last man standing against the establishment favorite for the GOP nomination. I don’t see that happening.  

Representative Steve King is making national news again, but in a new twist, for offensive comments about Jews rather than Latinos.

Speaking to Boston Herald radio on Friday, King said, “I don’t understand how Jews in America can be Democrats first and Jewish second and support Israel along the line of just following their president.” Over the weekend, apparently unaware that he had just validated a classic anti-Semitic trope about divided Jewish loyalties, King claimed that he was defending Israelis.

As my grandmother might have said, what King doesn’t know about Jews could fill a book. But after reflecting on the matter, I realized that King’s worldview is just as inexplicable to a typical American Jewish Democrat as mine is to him.

What’s on your mind this weekend? This is an open thread: all topics welcome.

The most important Iowa political story of the week was state Republican leaders hounding consultant Liz Mair out of a job with Scott Walker’s PAC. Colin Campbell compiled Mair’s tweets about the episode for Business Insider, and they are well worth reading. I’m still annoyed by the collective Republican temper tantrum and the Des Moines Register’s pandering.

A different Iowa political event drew even more attention, though, including a segment on ABC’s Good Morning America show. The fateful photo of Republican State Representative Ross Paustian might have been a footnote to a long Iowa House debate on a collective bargaining bill. But because the lawmaker was apparently reading a book called Sex After Sixty, the photo went viral and could easily become what Paustian is most remembered for when his political career is over. I enclose below background, Paustian’s explanation and a few thoughts on the sometimes cruel nature of politics.

New details have emerged about Governor Terry Branstad’s testimony in the lawsuit Iowa’s former Workers’ Compensation Commissioner filed three years ago, charging discrimination, defamation, and other claims. Ryan Foley of the Associated Press reported highlights from the transcript of Branstad’s deposition last November.

Are Iowans “government-dependent” types who should lose our first-in-the-nation status because we embarrass ourselves and the Republican Party?

No, but the way some people reacted to comments by a political strategist should embarrass Iowans and can only hurt the Iowa caucuses.

The next few weeks will be critically important for deciding whether Iowa keeps a statewide rule designed to preserve topsoil and reduce stormwater runoff, which carries pollution to our waterways. Bleeding Heartland discussed the 4-inch topsoil rule here and here. Todd Dorman has been on the case with several good columns for the Cedar Rapids Gazette, most recently here.

Follow me after the jump for background on the issue and details on how to weigh in. Submitting a comment takes only a few minutes, or Iowans may attend public hearings in Cedar Rapids tonight, Davenport on March 25, or Des Moines on March 27 (scroll down for times and locations).

Today the U.S. House passed a new version of a bill to change who can serve on the Environmental Protection Agency’s scientific advisory board. As happened last year, the Iowans split along party lines.
