I don’t see that they convinced a “large swath” of anything, except those that already wanted Trump impeached for breathing.

But it's also obvious that Schiff created this impeachable offense himself, using a lame attempt by the deep state to set up the quid pro quo narrative. It may be that some inept deep staters thought that Trump would not release the transcript. But he declassified it right away and proved them wrong.
This sorry follow-on coup attempt started right after the Mieller debacle At this point the deep state is in a panic. Plan C is next and Trump is a step ahead of that one. There's not much he could do against Weissman (besides ignore the stupid advice to fire Mueller). But he knew the outline of Plan B and had a counterplea.
