I mean we can't ignore the other side running garbage candidates either. DNC leadership doesn't care as much about their opposition party winning as they care about not losing leadership of their own party. That would mean all the established party politicians would be at risk of losing their job, where as republicans winning means they only lose a handful of positions while bolstering their next campaign season so they can push in more party toadies. Plus they are completely out of touch with the average American which makes their campaign messages and stated policies weak.
