As announced on the Heritage Foundation blog, Jim DeMint (R-SC) will leave the Senate to succeed Ed Feulner as the next President of the Heritage Foundation:
Heritage’s Board of Trustees unanimously chose DeMint as the organization’s next leader, starting April 3. DeMint will resign from the Senate and start as president-elect in early January, so he and Feulner can ensure a smooth transition. After April, Feulner will continue serving as Chancellor of the Foundation and Chairman of our Asian Studies Center.
…. Feulner, who announced three years ago that he would retire in April 2013, may be the hardest act to follow in Washington, D.C. Under his leadership, Heritage helped launch missile defense under President Ronald Reagan and welfare reform under President Bill Clinton and Speaker Newt Gingrich. During the past four years, Heritage has led a principled fight against Obamacare and has taken a lead in advancing the case for entitlement reform.
