These two maps are based on the famous final predictions made by Literary Digest (above) and Gallup, then known as American Institute of Public Opinion (below) in 1936. The predictions excluded minor parties and calculated the share of the major party vote in each state instead. This is based on the
report published by the
Pittsburgh Press the day before the election.
In addition to Connecticut and Rhode Island, Gallup also considered Illinois, Indiana, Iowa, Kansas, Massachusetts, Michigan, New Jersey, Ohio, Pennsylvania, South Dakota, West Virginia and Wyoming too close to call.
It's interesting that Gallup though largely accurate, gave a better result for the Republicans everywhere except North Dakota. The Republican best case scenario of all too close states going to them actually gives Landon a much better result (216 EV) than any of Roosevelt's opponents ever got.
