The fallacy in this statement is known as "Hasty Generalization." This fallacy occurs when a person forms a conclusion based on insufficient evidence or a small sample size. In this case, the statement generalizes the entire Republican Party and assumes that all the candidates running for president are "clowns." However, it is important to recognize that an individual's personal opinion of the candidates may not be representative of the entire party or its overall ability to govern. Therefore, it is unfair to judge the entire party based on a limited number of candidates. To avoid this fallacy, it is essential to gather more information about the candidates and their policies before making a conclusion about the future of the Republican Party.
