There have been two successful class warfare campaigns. Salena is mostly right in saying that TR and FDR did not engage in class warfare rhetoric, but not completely. Certainly the McKinley-Roosevelt ticket in 1900 and the Roosevelt ticket in 1904 did not; but TR's 3rd-party candidacy in 1912 dabbled in it. FDR in 1932, 1940 and 1944 did not, but his 1936 campaign was very much a class-warfare campaign, inveighing against "the malefactors of great wealth," and railing against "Martin, Barton, and FISH!" The great class-warfare victory, coming as it did as a surprise to most people, was Truman's victory over Dewey. That campaign was pure class warfare. 1936 and 1948 are the model. That model may or may not work.
