Corporatists corrupt both parties, and don't give a rat's ass about the political interests of either beyond exploiting them for power and profit. That is why the Koch brothers endorsed Clinton. She is a corporatist selling America to the highest bidder just like Biden.
They really are not. Corporatists are opportunists without sufficient morals, that will sell out their nation for the profit of the moment, without concern that the Marxists will slaughter all of their children when the nation coopted is conquered in full.
