Do you have a source for this assertion? So far as I have seen, Soros has donated more money personally than the Kochs have - but the Kochs have an extensive network of "grassroots" political organizations which in aggregate have funneled far money to politicians than Soros has done personally(on the order of hundreds of millions). I suppose at some level they are all using tricks and loopholes.
Clinton's FOIA emails are full of Soros literally giving orders to her and other reps. Use Wikileaks archive to read them/search for Soros.
He's also bought electronic voting corps and managed to get them into primaries like Utah. There were all kinds of shenanigans with them recently like denial of service to some voters.
This is a highly partisan site, but they do source most of their links. And keep in mind this is just a list of US political organizations he funds.
I'm not sure not what you mean by the Koch's extensive network. They're either giving their money, or it is other people's money. They can't be held responsible for how other people donate their money. I don't hold Soros responsible for all the ACLU's actions, even if he is a major backer. When they ACLU stands up for something I believe in, I donate, but I'm certainly [not responsible] for all their actions, especially in years I don't donate.
