I do not believe that any of this information would have changed a single Republican vote.

So in that timeline, the Senate would have ratified not just Trump’s Ukraine scheme, but even worse as acceptable behavior by an American president.

The practical effect of which would have been to reduce the constitutional mechanism of impeachment to its component atoms with no hope—none—of every reconstituting it…

I think about Bolton’s possible testimony the same way I think about the possibility of finding a tape of Trump saying the n-word:

If it had happened, then Republicans would have defended it and it would have collapsed yet another set of norms.

By not having it, we can at least hope that, at some point in the future, some of these norms might be restored.
