debate The two candidates traded barbs over past positions in a debate sponsored by Nebraska Educational Communications. Hassebrook accused Ricketts of supporting Gov. Dave Heineman's (R) tax proposal in 2013, which would have increased sales tax rates. The Platte Institute, a conservative think-tank created by Ricketts, supported the tax proposal, which ultimately failed to pass in the face of increasing public criticism. Hassebrook argued that Ricketts tried to hide his support for the measure when he decided to run for governor. Ricketts denied support for the bill, noting that he did not agree with every position taken by the institute. Ricketts countered by bringing up a report co-authored by Hassebrook in 1990 that called for a ban on exports of genetically modified crops. The issue of biotechnology in farming has grown in prominence due to the importance of Nebraska's agricultural sector. Hassebrook responded that he provided little assistance to the authors of the report, and was wrongly credited as a co-author. He also noted that he supported biotechnology research since the early 1990s, when he served on the University of Nebraska Board of Regents. Debate viewers also saw Hassebrook and Ricketts stake out distinct positions on immigration and the proposed Keystone XL pipeline that would run through Nebraska. Hassebrook advocated for allowing driving licenses for children brought to the country illegally, while Ricketts opposed issuing licenses as a matter of protecting existing laws. Ricketts suggested that the XL Pipeline would bring jobs to the state and securely transport oil across the country, citing problems with rail transportation of oil. Hassebrook opposed the pipeline because he suggested the project would contribute to climate change. Complete video of debate General election Candidates In Nebraska, gubernatorial nominees select their running mates after the primary elections. Pete Ricketts (Republican), former COO of TD Ameritrade and nominee for the U.S. Senate in 2006 Running mate: Mike Foley, Nebraska Auditor of Public Accounts. Ricketts had initially selected incumbent Lieutenant Governor Lavon Heidemann as his running mate, but Heidemann resigned from office and withdrew from the election on September 9, 2014, after allegations of domestic abuse. Ricketts named Foley as his new running mate within hours and, after some initial confusion as to whether Heidemann's name would still appear on the ballot, Secretary of State John A. Gale confirmed that the switch had been made to ensure "the accurate reflection of candidates on the ballot." Chuck Hassebrook
