Sanchez's political work began in the 1990s. While a student at GWU, she volunteered in several campaigns and acquired experience in this field. During this time, Sanchez went to work in the office of Rep.
Henry Bonilla, R-TX, as a legislative assistant on appropriations. Sanchez worked on border issues and immigration legislation. After college, Sanchez held several public relations and marketing positions in the Capitol and worked with the staff of
House Speaker Dennis Hastert. The results were tangible: "Until Leslie Sanchez, the Republican Party wasn't talking to
Univision," according to one colleague. The following year, Sanchez was asked by the 2000
Bush presidential campaign to work on Hispanic outreach. Together with
V. Lance Tarrance, Jr., a Republican pollster, Sanchez was a principal architect for two, "watershed Hispanic surveys," recognized as a thorough, political and cultural survey taken of Hispanic voters. Additionally, Sanchez helped create a multimillion-dollar RNC marketing campaign aimed toward the Hispanic market in key states during the 2000 election cycle. This program was cited as contributing to Bush receiving 37 percent of the Hispanic vote. This was the highest percentage of Latino vote for a Republican presidential candidate as of that time. On May 29, 2001, President
George W. Bush appointed Sanchez executive director of the
White House Initiative on Educational Excellence for Hispanic Americans. Created in 1990 by President
George H. W. Bush, the program's mission is to provide advice and guidance to the
Secretary of Education on educational issues related to Hispanics and means to address academic excellence and opportunities to the Hispanic community. In her role as director, Sanchez "monitored and evaluated Hispanic participation in education programs in 29 federal departments and agencies." Sanchez created a grassroots alliance of 20,000 students, parents, and educators nationwide, and assembled a strategic coalition of 30
Fortune 500 companies, financial institutions, and government agencies. Around this time, she entered the MBA program at Johns Hopkins University's
School of Professional Studies in Business and Education (now extant). On June 25, 2003, Sanchez resigned her White House Initiative position to form her own consulting firm, Impacto Group, LLC, the "first Republican political strategy and research group aimed solely at the U.S. Hispanic marketplace." Pollster Tarrance joined her as head of research and development for Impacto Strategies, a division of the Group, and chairman of its board of advisors. Impacto also deals with social and economic issues related to women. ==Consultant and commentator==
