This German newspaper article (translated by Deepl) claims that Democrats will defend Johnson against attempts by the right of his party to unseat him as speaker. I don't know the ins and outs of US politics, therefore I ask: What do you think?
Only if he makes a deal with Dems which makes him (politically) a dead man walking. Most likely they will just run out the clock until November when there are new elections. Republicans have a two seat majority out of hundreds, they can't do much without bipartisan support and that is not going to happen in this aggressive political atmosphere.
