1918 United States House of Representatives elections

Woodrow Wilson was elected to the presidency in the 1912 presidential election and his victory in the 1916 election made him the first Democratic president to win reelection since Andrew Jackson had in the 1832 election.^[1]

Wilson's wheat policies aided in the Democratic defeat. The Food and Fuel Control Act allowed for the cost of wheat to be set at a price control limit of $2.20 per bushel while other products like cotton were not. Wilson later vetoed an attempt by the Republicans to increase the limit to $2.40 per bushel. Republicans were more likely to gain seats in areas with higher amounts of wheat acreage with the Republicans gaining twenty-two seats in the ten highest wheat producing states while the Democrats only gained two seats.^[1]

Wilson was also unable to aid the Democratic candidates before the election due to his preparations for involvement in the Paris Peace Conference.^[1]
