Exactly.

Republicans nominate dangerously insane person to lead America, then panic when he proves he’s dangerously insane

They knew that about him when they nominated him. It’s too late to freak out about it now. They should have done that before they nominated him, not after.

Republicans have shifted into a much higher state of Red Alert because Trump’s erratic antics are revealing just how reckless their decision to nominate him really was, and how reckless their continued support for him really is. In other words, Trump is now threatening to damage the party in far worse ways than Republicans had bargained for, because he’s revealing in inescapably clear terms the real character and qualifications of the person they knowingly nominated to run the country and continue to support for the presidency.

All that was plenty obvious enough before the convention. He’s a terrible human being; he’s not subtle about it.

Trump’s pathologically abusive tendencies, his hair-trigger overreaction to criticism and slights both real and imagined, and his mental habit of sorting the world into the strong and the weak — the dominant and the submissive — render him temperamentally unfit for the presidency. He lacks basic knowledge of the world and doesn’t appear burdened by any curiosity about the complexities of foreign affairs or domestic policy. He is at worst a genuine bigot and at best a charlatan who has actively sought to stoke reactionary hostility to culturally and demographically evolving America. He is indifferent to the inner workings of the American system and instead promises authoritarian glory.

…

What’s really happened in recent days is that Trump’s ongoing battle with the Khan family only made all of these traits — the unhinged response to criticism, the bigoted attacks on Muslims, the naked abusiveness directed at a grieving family — more glaringly obvious. By extension, this has made nominating this man even more impossible politically for Republicans to defend. But Republicans knew who they were nominating. They themselves had repeatedly acknowledged that his personal traits were alarming and had castigated many of his positions as cruel and at odds with fundamental American values. Voices from all across the political spectrum, from liberals to centrists to Never Trump conservatives, warned that he would only get worse.

Now Republicans want to stage an intervention?

My point exactly.
