(from less than 60,000 in 1992 to more than 80,000 in 1994). She backed proposals to reduce the sale of semi-automatic firearms and "cop-killer" bullets in the state. She signed into law the amendment of the Texas Financial Responsibility Law where renewal of a motor vehicle's registration (also covers initial registration of a motor vehicle), safety inspection sticker, driver's license, and/or obtaining new license plates require that a motorist must have a valid auto insurance policy. The law, which passed on September 1, 1991, broadens the 1982 law where a police officer will request a driver's license and proof of insurance during a traffic stop. She appointed then State Representative Lena Guerrero of Austin to a vacancy on the Texas Railroad Commission. The Hispanic Guerrero (1957–2008) was the first non-Anglo to serve on the commission in history. However, problems over falsification of her resume led to her resignation from the commission and defeat by the Republican Barry Williamson in the 1992 general election. The Texas Lottery was also instituted during her governorship—advocated as a means of supplementing school finances; Richards purchased the first lottery ticket on May 29, 1992, in Oak Hill, near Austin. School finance remained one of the key issues of Richards' governorship and of those succeeding hers; the famous Robin Hood plan was launched in the 1992–1993 biennium and attempted to make school funding more equitable across school districts. Richards also sought to decentralize control over education policy to districts and individual campuses; she instituted "site-based management" to this end. In 1993, Richards signed into law the re-codified Texas Penal Code which included anti-homosexual Section 21.06, the state's "Homosexual Conduct" law which states: "(a) A person commits an offense if he engages in deviate sexual intercourse with another individual of the same sex. (b) An offense under this section is a Class C misdemeanor.". In 1990, Richards had campaigned in Houston to repeal the law. But, as governor, her signature criminalized same-sex sexual relations in Texas. In 1994, Richards ran for re-election against Republican George W. Bush. Despite outspending his campaign by 23%, she was defeated, with 45.88% of the vote to Bush's 53.48% while Libertarian Keary Ehlers received 0.64%. The Richards campaign had hoped for a misstep from the relatively inexperienced Republican candidate, but none appeared, while Richards created many of her own, including calling Bush "some jerk", "shrub" and "that young Bush boy".
