B. Voting rates are lower than in other democratic nations.
In many countries, enrollment is the first step to vote, for that you need to get register vote automatic. If you are the citizen of a country, you are signed up but the United States has no automatic enrollment system for a vote. You need to go to an official site like a library or a government office and fill out a paper form to register your vote. Comfortable enrollment could expect higher voting.
The other reasons are might possible, such as people don't want to cast their vote as the United States has only two political parties that are Democrats and Republicans or maybe people have not enough interest in politics.
