There should just be a general "voting" option; More votes as well as a handful of dedicated people (who have proved they know how to vote and do so fairly) who vote on every single debate that isn't rubbish. I find there's too many good debates that go unvoted unless the people involved are already popular on this site.
Some Big Issues i would like to see added are something about mass spying programs, Get rid of the border fence big issue and replace it with something of a broader immigration issue. I would like to see Campaign fiance reform come back as a big issue. Another issue i would like to see is free college education. A lot of issues are wars which should be replaced only with "Military offense" which i guess is military intervention. I would like to see sex education be added as one. And maybe even something on net neutrality. I would also like to see something to do with space like space exploration what people feel like the government doing by sending people to space. Theirs probably a few more they can take out and replace but the ones i listed are the ones that come to mind.
Well with creating an account as easy and liberal as it is ... Banning really has no lasting effect. Its like deporting someone and not having a wall to stop them from coming back in the very next day.
