Step-by-step explanation:
The attitudes developed as a campaign progresses and are often measured by opinion polls and surveys are public opinions. Public opinion is shaped by our upbringing, beliefs, and experiences, and it influences our attitudes and beliefs about political theory and policy. While attitudes and beliefs are slow to change, ideology can be influenced by events. Political scientists study when and why these changes happen and how they affect our opinions about government and politicians.
