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.
[1] Beliefnet identifies 12 main religious blocs in American politics, such as the "Religious Right", whose concerns are dominated by religious and sociocultural issues; and American Jews, who are identified as a "strong Democratic group" with liberal views on economics and social issues.
[2] The result is that each of these groups votes en bloc in elections.
Bloc voting in the United States is particularly cohesive among Orthodox Jews.
[3][4] Voting blocs can be defined by a host of other shared characteristics, including region, age, gender, education level, and even music choice.
