as anti-abortion, and pointed to legislation he signed that leaves "the final decision to a woman and her doctor". In August 2015, he criticized the notion that abortion is necessary to save the life of the mother in certain cases, calling it a "false choice." In an interview with the Milwaukee Journal Sentinel a few weeks before the November 2014 election, Walker declined to answer directly when asked if abortion should be prohibited after 20 weeks. In July 2015, Walker signed a state law banning abortion after 20 weeks, including in cases of rape or incest but excluding when immediate danger existed to the life of the mother. Criminal justice During his tenure in the state legislature, Walker campaigned on a "tough-on-crime" platform and sought to increase the length of criminal penalties by increasing mandatory minimums and by cutting parole possibilities. In 1996, he said, "The time has come to keep violent criminals in prison for their full terms." He advocated for privatization of prisons. Economy and budget As Governor of Wisconsin, Walker has received grades of B in 2012 and B in 2014 from the Cato Institute, a libertarian think tank, in their biennial Fiscal Policy Report Card on America's Governors. Wisconsin calls itself "America's Dairyland," with more dairy farms than any other state. In 2012, Walker instituted a program to encourage dairy farmers to dramatically increase production, which resulted in a supply glut and years of depressed prices. This had a crippling effect on the industry, leaving it vulnerable when in 2018 Canada, China and Mexico imposed tariffs on American farm exports in retaliation for tariffs imposed on them by President Donald Trump. The New York Times reported that by April 2019 Wisconsin dairy farmers were facing "extinction." Education Walker moved to weaken tenure for professors at the University of Wisconsin System and to cut its funding, while offering authority to reduce spending. He recommended deleting parts of the system's mission that contribute to the Wisconsin Idea. Parts of the mission proposed for deletion, such as the "search for truth," were to be replaced with a directive "to meet the state's workforce needs." Walker later called the change a "drafting error," but public records requests and litigation showed that Walker himself and his office were "the driving force" behind the changes. He supports the public funding of private schools and religious schools in the form of vouchers for
