By their answers to questions in debates, forums, or interviews which often are available online, voters can assess the degree to which the candidate understands the requirements of the office they are seeking. What are the candidate's qualifications for that office? Are they knowledgeable about the issues? Well-reasoned? Well-spoken?
Do you as the voter agree with the candidates' positions?
By their appearance, do they fit your expectations for the role for which they are running? If you expect a candidate to maintain a professional appearance, does he or she do so?
Are they presentable? Up to the demands of the position?
Are you able to get an impression of the character of the candidate? That may be difficult in-person or on a video. Check for further tips on how to research candidates at
