events, as he died of cancer that year. His death led to a temporary loss of leadership for conservatives within the party and further weakened their already inferior position. The dissertation draws from the papers and correspondence of Dewey, Taft, and their top lieutenants as they plotted and executed their strategies to secure the presidential nomination of the Republican Party in 1948 and 1952. It analyzes the public and private negotiations within these groups and their relationships with state and local party organizations around the nation.
