This isnt such a bad thing. Trump has run as an outsider. One of his strategies is to call out Hillary for taking money from donors who control her.
If he takes Koch money, he will be labeled a hypocrite. Let Koch fund the down ticket races and Trump can fund his run.
I don’t want Trump to get money from the Kochs but the Demagogues are going to have hundreds of millions going through SuperPACs to buy attack ads. The Kochs ought to counter that, unless they want to watch Shrillary be elected.
