A fifth column is a group of people who rationally and clandestinely tries to undermine a larger group to which it is expected to be loyal. The expression dates from the Spanish Civil War in 1936 when the Francoist General Mola, whose forces were threatening Madrid, boasted that he had four columns approaching the city and a fifth column within it.
During the Second World War, when British citizens were anxious about supposed fifth-columnists in the UK, the artist William Heath-Robinson produced a series of cartoons about the Sixth Column, patriotic men and women devoted to frustrating the actions of the Fifth Column.
In the United States, the Democratic Party has been considered America’s Communist Fifth Column, which is promoting Socialism.

The Communist Party USA’s national chairman John Bachtell acknowledged that the Democratic Party was its greatest ally, that is bent on destroying America from within its own infrastructure. In 2012, economist Peter Schiff, found that the majority of individuals within the Democratic National Convention’s delegation were enthusiastic supporters of outlawing profitability. As discussed in the cited article, the gravest threat to America's democracy is the Democrat Fifth Column.
