He's not unbiased, to be sure. He has an objective. It's apparently the same as Trump's. So Trump hired him to do this. Presidents get to do that (albeit, yes, they have to do it in the right way).
Soros isn't an evil Bond villain either. He's a rich guy who wanted to shape the way the U.S. operates and did. Just like the Koch Bros. did. I have no doubt that both Soros and the Koch's thought they were doing what was best for the common good. Just as I have no doubt the farthest left and the farthest right posters here at the Cooler want what is best for the common good as well, however they define it.
Well, except
@UncleMark. That guy's just an asshole.
