I mean, I agree with you. I'm just saying, along those lines, as far as the 30~40% holding steady support for Trump, I don't know that holding an intervention's going to work. Weaning them off of conspiracy theory masquerading as news is a bigger and longer battle, and probably involves some legislation.

In the short term, the important thing is holding Trump accountable. That means making congressional Republicans' position of enabling him a politically risky one. That doesn't mean convincing every Trump voter to stop watching Hannity and admit wrongdoing, it just means eroding "protect Trump from consequences" as a reliable strategy for riling up the base to vote in the midterms - it just means making them unsure. If they're falling back to "Hillary was worse", they're already conceding "Trump's doing something not great".

It might be effective against trolls, too. Anytime Trump makes the news, they throw out "what about Hillary", and people respond "Hillary doesn't matter", but they want to have the argument over whether or not Hillary matters, and present critcism of Trump as just partisan. Play devil's advocate - even if she were terrible, wouldn't we still want to hold Trump accountable?
