The danger: Parts of Trump America, canceled by Twitter and so many others, is severing its ties to the realities of the other Americas, and basically going underground. There will be less awareness and perhaps scrutiny of what’s being said and done.

Axios’ Sara Fischer reports that AppTopia shows a surge in downloads for conservative-friendly social networks — Parler, MeWe, and Rumble — in the past two days, following Trump bans by mainstream social media and tech.

The big picture: The Republican Party is splitting into two, starting with the relatively small Never Trumpers breaking off in 2016, and joined four years later by a new slice establishment Republicans repulsed by President Trump’s post-election actions.

We have no clue how big this faction will grow. But it seems clear that the Trump-vs.-them saga will dominate the coming months, and maybe years.
