I don't think the GOP isn't trying, but I think Russia in particular is just way ahead of the game where this stuff is concerned. Democrats in no way have a monopoly on just being coked-up boomers bouncing around Washington having no real coherent idea of what successful political strategy looks like and not really having to care. I think most of the successful non-mainstream-media manipulation and funding comes from outside the country, it just happens that what they want to happen lines up with promoting the GOP by coincidence.
