In the years that followed the Harrison campaign, many candidates—from Colonel James 'Young Hickory' Polk in 1844 to Lieutenant John Kerry in 2004—had their 'humble origins' and/or 'war leadership' highlighted in political material. Often coupled with these tactics was a corollary, to create an image of the opposition candidate that was highly negative—from John Adams as a 'monarchist' to John Kerry as a 'flip-flopping, windsurfing elitist.

Efforts by Democrats to portray Jackson as 'manly' and for the 'common man' were apparently more effective than were the campaign tactics of Adams’s supporters, who attempted to depict Jackson as violent, unjust, a paramour, and even a poor speller. It is quite possible that this anti-Jackson propaganda actually reinforced the positive image of Jackson as a masculine commoner—especially when contrasted with that of Adams, whom the Democrats depicted as an over-refined aristocrat.

Yet, some things do not change. Overall, designers have stayed with techniques that work—in different countries and historical periods. Flagg’s 'I Want You for U.S. Army' design in World War I, with 'Uncle Sam' looking directly at the viewer and pointing a finger at him, was derived from a British poster produced three years earlier; in the British poster, Secretary of State for War Lord Kitchener is pointing a finger at British males, with the words 'Wants You, Join Your Country’s Army! God Save The King.' Other countries—Italy, Hungary, Germany, Great Britain, Canada, France, the Irish Parliamentary Party, the Red Army in Russia, and later, the Republicans in the Spanish Civil War—designed similar posters. The British applied the same design idea in World War II, featuring Prime Minister Winston Churchill, instead of Kitchener, in the same pose; the U.S. Democratic Party resurrected Flagg’s Uncle Sam image, including it in an election poster for Franklin D. Roosevelt. In the decades that followed, however, anti-war protest groups issued satires of Flagg’s 'I Want You' poster, with 'Uncle Sam' in a variety of poses: pointing a gun at the audience; making the 'peace sign,' bandaged and accompanied by the slogan 'I Want Out'; as a skeleton, with a target superimposed on him; and with the 'bad breath' of airplanes dropping bombs on houses in his mouth.
