How Trump’s troll army is cashing in on his campaign

Google created an entire company that is essentially a 'Troll Army' for Obama during his second term and now Hillary.

Sanders has a 'troll army' built in to his campaign, because he has such a large percentage of tech-savvy youth, they flood most political discussions online, regardless if it's factual.

This is called politics. Every politician does this. I'm not sure why we are singling out Trump.
