Bennett's critics, including historians
James M. McPherson and
Eric Foner, as well as political scientist Lucas E. Morel, believe that he ignores Lincoln's political and moral growth during the course of the Civil War. In addition, they surmise that Bennett oversimplifies the complexities of the period on issues of race when criticizing Lincoln. They also point out many direct errors and manipulations in the work, such as switching Lincoln's yes and no votes as senator, quoting out of context and presenting false numbers. Unlike Bennett, they conclude that Lincoln was instrumental in creating the framework that emancipated the slaves in the United States. In a 2009 review of three newly published books on Lincoln, historian Brian Dirck referred to Bennett's 2000 work and linked him with
Thomas DiLorenzo, 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." ==See also==
