While more than 80 nationally prominent Republicans have signed on to a brief encouraging the U.S. Supreme Court to support marriage equality, Iowa Republican legislators continue to march lockstep behind efforts to overturn the Iowa Supreme Court’s Varnum v Brien ruling.

State Senator Mark Chelgren celebrated his 45th birthday last week with cupcakes for fellow senators and a promise that he will try to change an obscure part of the Iowa Constitution.

Legislators often introduce bills solely to make a political statement, but even in that context, Chelgren’s effort is an impressive feat of irrelevant grandstanding.  

The Iowa legislature’s 2013 session opened today. After the jump I’ve posted details on the Iowa Senate majority and minority leadership teams, along with all chairs, vice chairs, and members of standing Senate committees. Where relevant, I’ve noted changes since last year. Click here for a similar post on the new Iowa House.

Democrats hold a 26 to 24 majority in the upper chamber. The huge experience gap between the Iowa Senate caucuses is striking. Only seven of the 24 Republicans have served as lawmakers in either the House or Senate for more than four years, whereas 19 of the 26 Democrats have more than four years of legislative service. Click here for details on the tenure of all 50 Iowa senators.

Democrats will hold a slim majority in the next Iowa Senate: most likely 26-24 or 27-23, depending on the outcome of one recount and one special election in December. But the experience gap between the two parties’ caucuses is wider than I’ve ever seen, and perhaps unprecedented.

Only five Republicans who will serve in the next Iowa Senate have more than four years experience in the legislature’s upper chamber. Most of the old hands aren’t on the GOP leadership team. By comparison, eighteen Senate Democrats have held that office for more than four years. Thirteen of those have served in the upper chamber for at least a decade.

Many newcomers to the Iowa Senate have helped oversee public-sector budgets and programs as county supervisors, mayors, or members of city councils and school boards. Nevertheless, new legislators have a steep learning curve because state government is more complex than local government, and Iowa House and Senate members consider a wider range of issues during a typical legislative session. Whereas eleven Senate Democrats previously served in the Iowa House, only three sitting Republicans came to the Senate with that background. If the GOP had gained control of the upper chamber in this year’s elections, they would have been forced to put quite a few rookies in charge of standing committees.

After the jump I’ve posted details on the tenure of all incoming Iowa Senate members, indicating members of each party’s leadership team and past service in the Iowa House.

Three-time candidate for Iowa governor Bob Vander Plaats has made news this fall primarily on the “No Wiggins” campaign trail. However, the social conservative group he runs is supporting some Republican Iowa Senate candidates as well.

Last week the FAMiLY Leader launched radio advertising campaigns in two competitive Senate races–but notably, not in the district where Vander Plaats’ longtime right-hand man Matt Reisetter is running.  

Polls closed across Iowa at 9 pm, and I will update this post periodically as results come in from around the states. Any comments related to today’s elections are welcome in this thread.

P.S.- As expected, Wisconsin Democrats fell short in their effort to recall Republican Governor Scott Walker.

UPDATE: Results are after the jump.  

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.

Iowa’s well-documented problems with roads in disrepair and deficient bridges have prompted many calls for raising the gasoline tax in recent years. I’ve been skeptical that a divided state legislature would agree to raise an unpopular tax during an election year-session following redistricting. However, key lawmakers continue to insist that a gas tax hike is on the table. Arguments for why this proposal will and won’t pass are after the jump.

Republican Amy Sinclair and Democrat Dick Schrad have launched campaigns in the new Iowa Senate district 14, an open seat in south-central Iowa. Former Senate Minority Leader Paul McKinley lives in this district but decided not to seek a fourth term.

Follow me after the jump for a district map and background on the two declared candidates.

According to an Iowa House Democrats press release, Megan Day Suhr “announced today” that she is running for Iowa House district 28.
