Second tenure (2011–2017)
Branstad surpassed George Clinton's record as longest serving governor of the United States of 20 years, and 11 months, and 2 days on 14 December 2015.
On August 2, 2009, The Des Moines Register reported that Branstad was actively considering seeking the Republican nomination for governor. On October 7, Branstad filed papers to run for governor in the 2010 election. According to a September Des Moines Register poll, he maintained a 70% favorability rating from Iowans as compared to Governor Chet Culver's rating of 50%.
On June 8, 2010, Branstad won the Republican gubernatorial nomination, but when opposing candidate Bob Vander Plaats conceded, he did not endorse Branstad.
The Des Moines Tea Party gave Branstad a "no" on their report card regarding "criteria for acceptance" and said Branstad had "a history of raising taxes, [was] not a true conservative, increased the size of government every year he held office, [and] built a state-owned phone company." Former Iowa State Auditor Richard Johnson accused Branstad of keeping "two sets of books" on the state budget while governor. Johnson said Branstad needed to be "transparent" to Iowa voters about the reporting of Iowa's finances during his tenure as governor.
Branstad ran for reelection in 2014. He was opposed in the Republican primary by Tom Hoefling, a political activist and nominee for president in 2012 for both America's Party and American Independent Party. Branstad won the primary with 83% of the vote.
In the general election, Branstad faced Democratic nominee State Senator Jack Hatch and won with 59% of the vote.
Branstad rescinded an executive order signed by governor Tom Vilsack that restored voting rights to approximately 115,000 felons who had completed their sentences. Iowa was the last remaining state to have felons permanently disenfranchised until 2020, when Branstad's successor, Kim Reynolds, restored voting rights for some felons who had completed their sentences.
In June 2013, Branstad signed into law a sweeping tax reform bill that had widespread bipartisan support, passing the Iowa Senate by 44 votes to 6 and the Iowa House by 84 votes to 13. The bill, Senate File 295, provided for the state's largest tax cut in history, including an estimated $4.4 billion in property tax reform and an estimated $90 million of annual income tax relief, in part in the form of an increase in the earned income tax credit. The bill also included significant reforms to education and health care.
A June 2013 Business Journals analysis of 45 of the country's 50 governors ranked Branstad 28th in job creation. The ranking was based on a comparison of the annual private sector growth rate in all 50 states using data from the U.S. Bureau of Labor Statistics.
On April 13, 2017, with large Republican majorities in the Iowa legislature, Branstad signed a bill into law expanding gun rights, enacting a stand-your-ground law, expanding the right of citizens to sue if they believe their Second Amendment rights are being infringed, and expanding the gun rights of minors, among several other provisions.
Branstad's business-friendly appointments to the Iowa Utilities Board were controversial. They have "virtually assured" approval of the Iowa section of the Dakota Access pipeline. His last appointment was that of Richard W. Lozier Jr., who represented a pro-pipeline lobby group and who had to recuse himself one month after he joined in 2017.
On July 15, 2019, a jury in Polk County, Iowa awarded a gay former state official $1.5 million in damages, finding that Branstad had discriminated against him based on sexual orientation in 2012.
