Despite the threat and propaganda of World War II, voter turnout was a mere 33.9%. This is in stark contrast to other warring and Anglosphere nations during the period, with voting turnout being 71.1% in 1935 and 72.8% in 1945 in the UK; 69.9% in 1940 and 75.3% in 1945 for Canada, and 94.82% in 1940 and 95.13% in 1943 in Australia. This turnout was and still is historically low, with no other US biennial election yielding so small a turnout, although the 2014 elections remains a close second.[4][5]
^One Class 1 seat held both a regularly-scheduled election and a special election in 1942. This seat is not double-counted for the total number of seat contested.
