<P> 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 . For example, Beliefnet identifies 12 main religious blocs in American politics, including e.g. the "Religious Right", whose concerns are dominated by religious and sociocultural issues and "White Bread Protestants", who, while also conservative, tend to care more about economic issues . The result is that each of these groups votes en bloc in elections . </P>
