MTG filing a motion to vacate is at the behest of trump/putin. by removing the speaker, the GOP will go need to spend days or weeks finding a new speaker, until then any aid to Ukraine, Israel and Taiwan will continue to go nowhere.
fantasy-land: the Dem recruit 4 or more non-MAGA Repubs and elect a speaker of their choosing (i suspect it would need to be a Repub, despite the majority of the votes coming from Dems), one that will among other things bring the Senate's foreign assistance bill up for a vote.
Edit or they strike a deal with Johnson - you keep your speakership with our support in exchange for bringing up the aid bill immediately
