To accurately determine what the cartoonist is suggesting about moderate voters, it would be helpful to analyze the visual elements and captions of the cartoon itself. However, based on your description of the term "moderate" and common themes in political cartoons, one can infer a perspective.
If the cartoon depicts moderate voters with confusion, difficulty finding their place, or being overshadowed by extreme views, it could suggest that:
C. There are very few moderate voters today.
If the cartoon shows moderate voters actively participating and influencing the political scene, it would suggest that they are significant in number.
Without seeing the cartoon, I cannot provide a definitive answer, but typically, political cartoons comment on the current climate. Based on common interpretations, option C might be the more likely suggestion if the cartoon reflects themes of polarization or marginalization of moderate views.
