Ideally that wouldn't matter. People who care about an issue would vote on it.
That opens another can of worms, though - not enough people know or care about issues that will directly or indirectly affect them. People who do usually have some vested interest at stake.
The key to success IMO for a system like this is preventing the real-world equivalent of bots and voting rings. Bots are one thing, but I'd imagine voting rings would be very difficult to mitigate in a system like this. I guess it depends on the parties involved raising awareness effectively.
