Henry Wallace was once a friend of Truman’s but had become radical, and in some quarters, was considered a Communist. Truman’s great fear was with the Democrat Party effectively splitting into three factions, one moderate, one right of center, and one left of center, the Republicans would have a cake walk. In fact one newspaper called for Dewey before all the results were in, so convinced were they Truman had lost. This is an important reason why Third Parties can be instrumental in the incumbent President losing the election. Truman won and was able to continue his plan of following New Deal principles laid down by former President Roosevelt.
James Madison had always maintained, however, that majority rule was against the principles laid down by the Founding Fathers. With majority rule, one party and then the other, may achieve an unassailable majority to enact controversial legislation. Madison believed people should stand for a time as representative of their community, and in turn elect senior law makers and governors who would quorum to enact legislation. Once these people had served, they returned to lives in the local community, thus making them reflect the interests of their constituents rather than some spurious political ideology compelled on them from above.
