Is there anything in the Constitution that prohibits an ex-president from being elected VP?
If not, if said ex-president was elected twice would that make him/her ineligible to be elected VP?
I’m not entirely sure, since that’s not spelled out clearly. However, the problem is that if a former two-term President decided to accept a VP slot, he’d have to be prepared to serve as President in case of something happening to his running mate, in which case, his succeeding him would seemingly be a violation of that Constitutional Amendment. If he was able to serve out 8 years as VP without having to step in, then it should be Constitutional. It’s a bit of a grey area.
Reasonable minds may disagree on this, but I will tell you my opinion after long and careful thought over the past 12 years or so:
1. The 25th Amendment does not prohibit a two-term president from ever again acting as president, only from ever again being elected president.
2. The 12th Amendment provides that no person constitutionally ineligible to the office of president is eligible to the office of the VP.
3. Given that a two-term president is not constitutionally ineligible to the office of the presidency, he is not constitutionally ineligible to the office of the VP.
4. Since a two-term president is not constitutionally ineligible to the office of the VP, and there is no constitutional provision prohibiting certain persons eligible to serve as VP from being elected VP, a two-term president may be elected VP.
