If you're a piece of shit corrupt politician, he's a godsend. He's loud and distracting, corrupt as hell, doesn't give a fuck about any sort of ethics as long as he's getting his, plus he's dumb as shit and has a massive ego. The amount of mid-level corruption you can get away with while everyone's looking at Trump has to be insane, and all you have to do is chuck him a wad of cash or tell him he's great once or twice a year.

They're going to prop him up for as long as they can, make out like bandits and when his cholesterol finally catches up to him and he dies, they'll all scuttle off back into the woodwork and in ten years you won't be able to find anyone who admits to having supported him at all.
