I had a long reply mostly written until I came across this on the Wikipedia article on the Gore v Bush circus; "Though Jeb Bush recused himself from involvement in the recount, Democrats alleged there was still an appearance of possible impropriety."
So your point is moot, Jeb did recuse himself and Judge Leslie Abrams, the sister of the Democrat candidate Stacey Abrams, has not.
His secretary of state, I forget her name, still oversaw the recount. Has anyone asked the sister to withdraw?
