In his latest Baltimore Sun commentary, “Newt Gingrich Is the GOP’s Only Serious Candidate,” UMBC political science professor Thomas Schaller argues that despite claims of his unelectability, Gingrich stands out as unique in the GOP presidential field. Schaller calls Gingrich “the Republicans’ one-man walking, talking think tank” and argues, “he will be able to conduct a serious debate about America’s future because he’s the only GOP contender who has spent the past three decades actually pondering the problems, large and small, facing the country.” Read the column to learn more about Schaller’s 2010 interview with Gingrich and their conversation on Gingrich’s book “To Save America.”
