How do differing political views lead to greater political participation?

Personally, I believe that differing political views result in greater political participation because of a persons need to help the side they support win. Take this for example: Republican and democratic parties have come to an issue where they see two completely different solutions. The republicans are scared that if they don't have great amounts of participation, the democrats will win and the democrats are scared of they don't have great amounts of participation, the republicans will win. This need to help the idea they support win drives a greater amount of political participation form both sides and is applicable to any differing political views. Hope this helps! :)
