Important information when researching a candidate is:
Their biography: because it tells us about their qualifications, studies, job experience, and even intimate details that can give us a clue about their thoughts and views.
Their voting record: it is likely that a political candidate has been a public official before. If this is the case, researching their voting record can help us understand if what they claim they think is consistent to how they vote in the public sphere.
Their proposals: finally, every candidate has a set of proposals that should form a coherent view. It is important to investigate the candidate's proposals, taking into account that all of them will not necessarily become true if the candidate is elected.
