Responsibility

It is our responsibility as adult US citizens to vote. I know that many people don't, for whatever reasons they may have. I encourage people to take an interest in and be part of the process. I know that we all want our votes to count, but it seems as though there have been some concerns that at times in our history, some votes have not been counted. What is wrong with our system? It doesn't seem like it would be that hard to make sure the voting is done in an ethical manner. What do you think?
