Doing the Depression, when the original Gallop Polling  system was being developed the odds on favorite was the Republican running against FDR. Gallop pioneered the anonymous phone poll, asking the same questions of people regardless of  race, income or occupation. Early Gallop  polls  had FDR comfortably ahead, which was considered impossible by the news papers and Washington  elite because opinions of blacks, women, or the unemployed simply didn't count, just as they still dont count now if they support Trump.
