A voting bloc is a group of voters that are strongly motivated by a specific common concern or group of concerns to the point that such specific concerns tend to dominate their voting patterns, causing them to vote together in elections. Frequently blocs come from the same community or have the same interests. Voters in a bloc tend to vote in the same or similar ways. These blocs tend to band together to campaign for a common interest or major issue. Blocs are used to allow a collection of voter to gain more leverage over elected officials by showing a significant portion of voters care about a major issue, allowing for a display of the ability of voters to maintain votes over specific issues from election to election.
