The following pictures are political cartoons of President Truman presidential campaign in 1948.
In this picture you seen Truman and Barkley. I believe Wallaceites were democrats. The G.O.P is the Republican Party also commonly called the Grand Old Party. The Rebel Democrats were the southern democrats. They are depicted as the enemy because they were against Truman in the campaign. This political cartoon message is showing that Truman was against the Republicans, Southern Democrats, and Wallace. The Charge of the Little Brigade relates to this because in the charge a small cavalry with bravery carried out their orders against a stronger outnumbered enemy regardless of the outcome. In this picture Truman is against many as well.
In this picture Dewey appears a lot. Dewey was the man running against Truman. Thomas Dewey was from the Southern Democrats. He appears in the cartoon to the right believing that he will win the election. However Truman won the election easily, it was not close. According the cartoon in 1948 Dewey was predicted to win the election against Truman. In the picture Truman seems worried and annoyed from Dewey who is smiling because of the bulletin board. Every single message on the board predicts a dominant win over Truman.
The significance of the overturned cart is to show that Truman did not believe or cared about the polls, trends, betting odds, expert opinions, and predictions. You can also see apples appear next to the predictions. This cartoon may have been created after the election or towards the climax once they flipped the campaign by beginning to get all the votes and wins. The message of this cartoon is that Truman overcame everyone who said he was going to lose the campaign. Everyone was wrong about him ever going to lose. The most significant words were betting odds which shows that the cart contained the things against him.
