I am saying "ALLEGEDLY" because I am shocked if that's true. Not that they despise nationalism but that they were not extreme right-ring Conservatives. So they are not fans of the Donald John Trump and I expect he is not a fan of theirs. Well he is not of a fan of anyone but himself so that's no surprise.
The Koch Brothers are way way way way way way way richer than the puny tiny liddle Donald John Trump. Think he'd battle them anyway? Remember the song about the ant and the rubber tree plant? The ant had high hopes he take down that plant. In a contest to the figurative death who'd win? The Koch Brothers or the Donald John Trump?
By the way the Koch Brothers support a lot of Public Television programs that I enjoy. Another shock for me. They are not one-dimensional anything. Who knew?
