Other Possibilities
With it becoming more likely everyday, that Sleepy Joe will either resign or be removed before year end, there are two possibilties for getting Kamala out of the line of succession. If another Republican SCJ gets bumped off(like Scalia) Joe can nominate her to open things up for the new chosen successor. If she won’t go along with that option, Plan B might be to have her succumb in her sleep one evening. Either way they avoid those critics who would complain that primary challenges by more qualified sitting governors were racist and or misogynist.
