Literally anyone in the world can somehow have influence over how people think about candidates and how they will vote.
Is this a good or bad development in your opinion?
I can almost only see negative effects right now since people tend to believe almost anything they read.
I think we all know someone that read "something" on Facebook and just took it as truth and started spreading the word.
It's a scary thought that first of all you can have people believe whatever you want due to human nature, but even scarier that thanks to the internet it can be done on a global scale almost instantly.
