There are two main parties in the US, Republicans (represented by an elephant symbol, and red color) and Democrats (denoted by a donkey and blue color). These parties have antagonizing policies. For instance, Republicans believe in a small government, low taxes, pro-life, and in the 2nd Amendment. Democrats advocate for a large government, high taxes, pro-choice, and gun control. Running a Presidential campaign is a daunting task because one must not only know about the policies but also the trends.
