you have every right not to vote. But at this time in history there IS a difference between the parties and yes your vote counts. You really only have one responsibility as a citizen, voting. If you don't think that works, find a candidate you can get behind and volunteer for them, find out how it works from the inside.

Also, your vote is extra powerful on the local level. For example, are crackpots trying to take over your school board? Your vote might make the difference.
