Assume for a moment that Donald Trump survives the Russia investigation.
Assume first that he doesn’t fire Robert Mueller. Assume then, as seems increasingly likely, that Mueller discovers a web of financial entanglements between Trump and Russia, that he can show how Russia thought they had leverage over Trump and used every weapon in their cyber arsenal to get him elected.
But also assume that Mueller was unable to find any smoking gun evidence that Trump, his family or his campaign coordinated with the Kremlin beyond the Donald Jr. meeting we now know took place.
Will this benefit or harm the President politically as he moves toward reelection in 2020?
