VPs rarely go on to be President...so I worry about Vance as VP.
I would vote for whomever got the nomination. I'm sure not going to vote for a Democrat.
Statistically, you are wrong.
of the 45 men who have been US Presidents, 44 of which could have served as VP Prior(obviously Washington could not have served as VP Prior), 15 were VP prior to being POTUS. This translates to an approx 34% of our POTUS being VP Prior.
Yes, most of them are due to death, but that was not excluded from your “rarely”
Excluding death and Ford, 6 of the 44. Still a 1 in 8 chance(approx 13%)
To me, that is not rarely.
If you want to check, 2,3,8,37,41,46 were all prior VP’s and did not ascend due to death.
This all said, JD is a toss up. The political landscape will change in the next two years and who knows what evil the dems will cook up.
