Yes, all of these.

But I don't think they are unaware of these methods or unwilling to play dirty. I think that's just a cover. I'm convinced they simply don't want to do any of that because on the whole, their donors are either okay with the fascist agenda and/or believe they can get back in power by default because of Trump's fuckups. Thereby going back to business as usual without promising any significant concessions to their voters. E.g. none of that Medicare for all shit. After two years of the fascists people would be happy to lap up anything that looks even remotely better. See how happy Booker's performance made people. It's something and people will take it over nothing.
