Groups of like-minded voters, also known as 'blocs', are a common phenomenon in politics. Blocs are formed when a group of people with similar interests and beliefs come together to support a particular candidate or party. These blocs can be powerful forces in elections, as they can sway the outcome of an election by providing a unified voice for their cause. Blocs can also be used to influence policy decisions, as they can provide a unified voice for their interests and beliefs.
