House seats don’t do governor appointment like senate seats (nor would you want Glenn Younkin to make an appointment). They are just vacant until a special election. She’s been able to keep up for a while - even fairly recently - from what I had seen (using text to speech to deliver speeches/interviews and the like). I’m not sure what her current state looks like now though
Suhas Subramanyam won the seat this year, someone else will fill in fact fill the seat soon enough
They’re planning on voting again
They were just a few votes short of the threshold
