If people would stop replying to he/she/it's posts and just click the "report" button, he/she/it would eventually go away. Trolls are looking for recognition, and without it they disappear. I don't know why it's so hard for people to understand this.
As far as I know, there is no way for a person/group to put an issue on the ballot at the federal level, like you can in some states.
I'd imagine that it would take a constitutional amendment to change that, and I don't see the politicians ever doing that.
Aren't all members of Congress supposed to be "equal", and all have access to the same information? Would it not be illegal, or at least against the rules, to withhold information from other members of Congress?
