debated Claremont Institute fellow professor Harry V. Jaffa on the merits of Abraham Lincoln's statesmanship before and during the Civil War. DiLorenzo's book, Lincoln Unmasked: What You're Not Supposed to Know About Dishonest Abe (2007), continues his explorations begun in The Real Lincoln. In a review, David Gordon stated that DiLorenzo's thesis in the 2007 volume was that Lincoln opposed the extension of slavery to new states because black labor would compete with white labor; that Lincoln hoped that all blacks would eventually be deported to Africa in order that white laborers could have more work. According to Gordon, DiLorenzo states that Lincoln supported emancipation of slaves only as a wartime expedient to help defeat the South. Reviews in The Washington Post and Publishers Weekly both stated that the book seemed directed at unnamed scholars who had praised Lincoln's contributions. Justin Ewers criticized DiLorenzo, saying this book "is more of a diatribe against a mostly unnamed group of Lincoln scholars than a real historical analysis. His wild assertions – for example, that Lincoln held 'lifelong white supremacist views' – don't help his argument." Publishers Weekly described this as a "screed," in which DiLorenzo "charges that most scholars of the Civil War are part of a 'Lincoln cult';" he particularly attacks scholar Eric Foner, characterizing him and others as "cover-up artists" and "propagandists.". Conversely, The Independent Review states that the book "manages to raise fresh and morally probing questions" and that DiLorenzo "writes primarily not as a defender of the Old South and its institutions, culture, and traditions, but as a libertarian enemy of the Leviathan state" but bemoans that DiLorenzo was "careless" in his handling of sources and despite his "evident courage and ability", his execution was lacking. In a 2009 review of three newly published books on Lincoln, historian Brian Dirck linked the earlier work of Thomas DiLorenzo with that of Lerone Bennett, another critic of Lincoln. He wrote that "Few Civil War scholars take Bennett and DiLorenzo seriously, pointing to their narrow political agenda and faulty research." In his book "Hamilton's Curse: How Jefferson's Arch Enemy Betrayed the American Revolution--and What It Means for Americans Today" expands on DiLorenzo's libertarian, small government views and details ideological differences between "Hamiltonians" and "Jeffersonians" in the role of the central government. Controversy over League of the South involvement Controversy arose in 2011 when DiLorenzo testified before the House Financial Services Committee
