He is a graduate of the
University of Michigan and
Harvard Law School. From 1967 to 1970 Wertheimer was Legislative Counsel to Representative
Silvio Conte (R-MA) and Minority Counsel to the House Small Business Committee. In May 1971, he started working for
Common Cause, a nonpartisan citizens' lobby where he was assigned to the issues of
campaign finance reform and ending U.S. involvement in the Vietnam War. In 1976, Wertheimer was legal counsel for Common Cause during the
Buckley v. Valeo case. He worked there until 1995, serving as Legislative Director, Vice President for Program Operations and as President from 1981 to 1995. In 1982, he was elected to the Common Cause National Governing Board. Through Common Cause, Wertheimer sought legislation regulating
special interest groups and
political action committees. During his twenty-four year tenure at Common Cause, Wertheimer led the organization's successful campaign to pass the
Federal Election Campaign Act (FECA), creating the current system of public financing in presidential campaigns. Wertheimer also led Common Cause's successful battles to enact comprehensive ethics and
open government laws for Congress and the executive branch, and was a "key architect" of the nuclear arms control coalition in the 1980s, according to
Congressional Quarterly. He also helped to create and publish
Common Cause magazine, which won the National Magazine Award for general excellence in 1987. He was succeeded in 1995 by
Ann McBride Norton. In 1996, Wertheimer was a Fellow at the
Shorenstein Center on the Press, Politics and Public Policy at Harvard University, and in 1997 he was the J. Skelly Wright Fellow and Visiting Lecturer at
Yale Law School. He also has been a political analyst and consultant for
CBS News,
ABC News and ABC's
Nightline. Wertheimer is currently the President and CEO of
Democracy 21, a nonpartisan nonprofit organization, which he founded in 1997. He was named as one of the 90 greatest Washington lawyers of the last 30 years by
Legal Times (2008) and as one of Washington's top lobbyists by
The Hill, a Capitol Hill newspaper (2009, 2010 and 2011). Democracy 21 and Wertheimer played major roles in the enactment of the
Bipartisan Campaign Reform Act in 2002 (BCRA), the
Honest Leadership and Open Government Act in 2007 (HLOGA), the establishment of the
Office of Congressional Ethics in 2008, and House passage of the
DISCLOSE Act in 2010. ==Awards and honors==
