Tonight may be the last chance for Rick Santorum or Newt Gingrich to stop Mitt Romney from becoming the Republican presidential nominee. Senator Chuck Grassley hinted to The Hill today that he may endorse Romney if Romney wins the Ohio primary. I’m guessing that Newt will pull enough votes in Ohio to keep Santorum from beating Romney. I also suspect that Santorum will lose the Catholic vote in Ohio, like he did in Michigan. He and Gingrich have to hope that convincing victories in southern states give them an excuse to stay in the race.

I’ll post results from all the Super Tuesday states after the jump. Any comments about the presidential campaign are welcome in this thread.

Last month President Barack Obama nominated Stephanie Rose, U.S. attorney for Iowa’s northern district, for a federal judgeship in Iowa’s southern district. If confirmed, Rose would become the first woman to serve as a district judge in Iowa’s southern district. Today the Des Moines Register published an opinion piece urging U.S. senators not to “rubber-stamp” Rose’s nomination.  

Two-term Democratic State Senator Tom Rielly announced today that he will not seek re-election in the new Iowa Senate district 40. That seat was arguably the Senate Republicans’ best pickup opportunity even before Rielly confirmed his retirement plans.  

Democratic Congressional Campaign Committee officials have not commented publicly on State Senator Joe Seng’s possible challenge to Representative Dave Loebsack in Iowa’s second district. However, the DCCC has commissioned a robo-poll on the potential IA-02 primary.

Governor Terry Branstad’s approval ratings were mediocre during the first year of his fifth term, but the latest Des Moines Register poll by Selzer and Co found that 56 percent of Iowa respondents approve of the job Branstad is doing, while 58 percent have a favorable impression of the governor.

NOTE: On March 12, Democrat Shelley Parbs announced her candidacy in this district, and a third Democrat, Nick Volk, filed nominating papers on March 15.

Iowa Senate Democrats finally announced their challenger to first-term Republican Tim Kapucian last week, setting up a potentially competitive race in the new Iowa Senate district 38.

Lots of court-related news is on my mind this weekend. I’ve posted links on upcoming trials and likely future lawsuits after the jump.

All topics are welcome in this open thread. History or photography buffs may enjoy the Retronaut’s post featuring pictures of photographers holding their most iconic images.

Competitive primaries can be healthy. I believe Democratic Party leaders made a mistake in discouraging Christie Vilsack from running for Congress in Iowa’s new second district. I don’t have any grudge against Representative Dave Loebsack–I just felt Vilsack could be a good fit for the district and had every right to run where she had the best chance of winning.

The idiocy of the incumbency protection racket doesn’t make every primary challenge logical. Ed Tibbetts reported yesterday on one of the most ludicrous ideas I’ve heard lately: a Congressional bid by Democratic State Senator Joe Seng of Davenport.

Two Republicans are running against Representative Bruce Braley in Iowa’s first Congressional district. Up to now, both have focused on criticizing the incumbent, President Barack Obama, and Washington political culture.

In recent weeks, Rod Blum has started making the case against his primary rival, 2010 GOP nominee Ben Lange.

The U.S. Senate voted today to table Republican Senator Roy Blunt’s amendment to repeal a federal regulation on birth-control coverage in employer-provided health care insurance. Iowa’s senators split on party lines.

UPDATE: Added a statement from Tom Harkin below. He argues that the Blunt amendment goes way beyond coverage of contraception and other preventive health services.

One of Representative Dave Loebsack’s three Republican challengers just announced that starting today, he will be campaigning full-time in Iowa’s new second Congressional district.

The Iowa delegation split on party lines yesterday over a bill designed to give California farms more access to water in the San Joaquin Valley. The bill would overturn Obama administration regulations designed to protect endangered fish populations.

All 40 Iowa House Democrats left the state capitol this morning to protest Republican House leaders’ plans to debate a bill and a proposed constitutional amendment that are among gun advocates’ highest legislative priorities.

UPDATE: Democrats returned late in the day, and I’ve added details below on the House floor debate and passage of both bills the evening of February 29.

The U.S. House voted yesterday to repeal two regulations enacted by the Obama administration’s Department of Education. Bruce Braley (IA-01), Dave Loebsack (IA-02), and Leonard Boswell (IA-03) were among 69 House Democrats who joined a united House GOP caucus in supporting this bill.  

Polls just closed in Michigan and will close in an hour in Arizona. Mitt Romney’s fighting for his political life in the state where his father used to be governor. I cannot believe that someone who’s been in politics as long as Romney says things like my wife “drives a couple of Cadillacs” and “I have some great friends that are NASCAR team owners.”

I love how Rick Santorum’s campaign robocalled Michigan Democrats seeking their votes in the primary because Romney opposed the bailout of U.S. automakers. The call didn’t mention that Santorum also has spoken out against that bailout.

I’ll update this post later with results. Meanwhile, any comments about the Republican presidential race are welcome in this thread.

UPDATE: Romney is easily winning Arizona with 49 percent of the votes to 25 percent for Santorum, 16 percent for Newt Gingrich, and 9 percent for Ron Paul. LATER UPDATE: Final Arizona results: Romney 47, Santorum 27, Gingrich 16, Paul 8. Romney gets all 29 delegates from the state.

With about three-quarters of the Michigan votes counted, Romney’s the projected winner with 41 percent to 37 percent for Santorum, 12 percent for Paul, and 7 percent for Gingrich. LATER UPDATE: With almost all the votes in, Romney’s at 41, Santorum 38, Paul 12, Gingrich 7. It’s not clear yet whether Romney or Santorum will win more delegates, which are assigned by Congressional district in Michigan. Exit polls suggest that Romney carried the Catholic vote in Michigan, which means it wasn’t too smart for Santorum to attack JFK during the final week of the campaign.

In a CNN interview, Paul denied that he is “in cahoots” with Romney.  

The Democratic-controlled Iowa Senate passed two bills today favored by corporate agricultural interest groups. House File 589, the notorious “ag gag” bill, seeks to prevent whistleblowers from reporting alleged abuse at agricultural facilities. Senate File 2172 would reduce the number of sows that confined-animal feeding operations need to report for manure management purposes. Details on the bills and how senators voted are after the jump.

UPDATE: Bypassing normal legislative procedures, the Republican-controlled Iowa House also passed the “ag gag” bill on February 28. Scroll down for details on how the state representatives voted.  

Republicans have recruited a strong candidate for the open Iowa House district 14, which covers most of Sioux City’s west side, part of the north side and some of the downtown neighborhood.

Des Moines was second only to Washington, DC in the latest Forbes magazine report on the best cities for high-paying jobs.

A majority of Iowans oppose a constitutional amendment to ban same-sex marriage, according to the Des Moines Register’s latest statewide poll.

Christie Vilsack toured Iowa’s new fourth Congressional district late last week to roll out an energy plan “geared towards bringing a new prosperity to Iowa’s small cities and rural communities by creating layers of economic opportunity.”

The five-point plan is more of a political statement than a detailed policy document. Like some of Vilsack’s previous proposals, it embraces some Republican talking points.

Upon closer examination, the energy plan looks like two parts bipartisan no-brainers, two parts conservative buzzwords, and one part fairy dust.
