Last night the Iowa Senate approved Senate File 296, a bill to expand Medicaid, on a strictly party-line vote of 26 to 23. You can listen to the entire Senate debate (approximately 90 minutes) at Radio Iowa. I’ve posted highlights from the debate after the jump, along with the full list of 52 organizations that have registered their support for Senate File 296. Some corporations and organizations have have registered their lobbyists as undecided on Senate File 296, but at this writing, not a single organization is registered against the Medicaid expansion.

Governor Terry Branstad traveled to Fort Madison yesterday to discuss a fertilizer plant project involving the largest tax incentive package in Iowa history. Previewing a likely theme of his re-election campaign next year, Branstad spun questions over his administration’s handling of the Orascom deal into an attack on Iowa Senate Democrats and the Koch brothers.

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.

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.

Republicans saved the day for Iowa Senate Commerce Committee Chair Matt McCoy, providing most of the votes he needed to drag the nuclear energy bill over the line on Tuesday.

Expanding nuclear power is again a hot topic at the Iowa statehouse. It’s not clear whether Iowa Senate Commerce Committee Chair Matt McCoy can find the votes he needs to advance House File 561. McCoy announced last week that new language in the bill would protect consumers and satisfy a majority of his committee members. However, opponents say the changes address only one of many problems in a bill that would primarily benefit MidAmerican Energy at the expense of its ratepayers. McCoy was forced to delay consideration of House File 561 on March 8, but he is expected to bring up the bill before his committee sometime this week–if he has the votes.

Follow me after the jump for analysis on the prospects for passing House File 561 and the merits of the bill.

The November special election in Iowa Senate district 18 confirmed that Democrats will maintain a 26 to 24 majority in the upper chamber during the legislature’s 2012 session, set to begin on January 9.

Senate Democrats and Republicans recently announced updated committee assignments. Majority and minority leadership teams are after the jump, along with all members of standing committees. I’ve also noted which senators are up for re-election in 2012 and which are retiring next year.

Former Minnesota Governor Tim Pawlenty endorsed former Massachusetts Governor Mitt Romney for president this morning, trying to set the media agenda as eight Republican candidates prepare to debate in Florida this evening.

Backers of former Minnesota Governor Tim Pawlenty’s presidential campaign insisted all summer that he would stay in the race at least through the Iowa caucuses, but he gave up this morning.

The Des Moines Register’s new poll of 400 likely Republican caucus-goers indicates that Representative Michele Bachmann is gaining ground. Selzer and Co surveyed Iowans between June 19 and 22, and the margin of error for the sample of likely caucus-goers is plus or minus 4.9 percent. Former Massachusetts Governor Mitt Romney leads the field with 23 percent support, but he has already indicated that he won’t invest heavily in Iowa this cycle. Bachmann nearly matched Romney in the Register’s poll with 22 percent. Former Godfather’s Pizza CEO Herman Cain placed a distant third with 10 percent, followed by former House Speaker Newt Gingrich and Representative Ron Paul (7 percent each), former Minnesota Governor Tim Pawlenty (6 percent), former U.S. Senator Rick Santorum (4 percent) and former Utah Governor Jon Huntsman (2 percent).

Romney’s best numbers are among moderates, people with less than a college education, and those earning less than $50,000 per year. Bachmann did particularly well with respondents who are very conservative, well-educated and/or between the ages of 45 and 64. The encouraging poll numbers will give her more buzz just as she is scheduled to formally announce her candidacy (for the second or third time) in Waterloo on June 27.

The results are terrible for Pawlenty, who doesn’t seem to be getting any traction out of his large staff and many Iowa visits. Putting a less-bad spin on the numbers,

Republican pollster Randy Gutermuth pointed out that the Iowa Poll took place before Pawlenty’s television ads, direct mail and other paid voter outreach had time to penetrate.

“It’s way too early to be writing off Tim Pawlenty,” said Gutermuth, who is not affiliated with any presidential candidate. “I’m sure they’d rather be leading today, but I don’t think they’re jumping out of buildings either.”

Maybe not jumping out of buildings, but eager to change the subject as soon as this poll came out. On June 26, Pawlenty’s campaign announced the formation of an Iowa Legislative Steering Committee. Legislators serving on the committee cover all regions of the state: Iowa Senators Randy Feenstra (district 2), Rob Bacon (district 5) and Shawn Hamerlinck (district 42), and State Representatives Chip Baltimore (district 48), Joel Fry (district 95), Erik Helland (district 69), Chris Hagenow (district 59), Steve Lukan (district 32), Linda Miller (district 82) and Matt Windschitl (district 56). Unfortunately for Pawlenty, all the endorsements in the world won’t turn things around unless the candidate starts connecting with caucus-goers. Right now Bachmann leads him even as a second choice for Iowans who prefer Romney–and that’s without any of the candidates picking apart Pawlenty’s fiscal record and heavy state borrowing.

Speaking of the Register’s opinion polls and caucus coverage, the Sunday paper announced that Jennifer Jacobs will be the Register’s chief political writer. She replaces Thomas Beaumont, who took a job with the Associated Press this spring.

Any comments about the Republican presidential race are welcome in this thread.

UPDATE: Douglas Burns tells us what a top British bookmaker says. Even before this poll was released, Ladbrokes gave Bachmann the best chance of winning the Iowa caucuses.

SECOND UPDATE: More detailed questions results from the new Iowa poll are here. I’ve highlighted some interesting results from the “issue” questions after the jump.

On a party-line 26 to 23 vote, the Iowa Senate today approved a bill to restrict the locations of clinics where abortions are performed after 20 weeks gestation. Senators also rejected an attempt to bring up a broader ban on abortions after 20 weeks.
