So this articles theory kind of skirts around the 25th amendment. It understands the 22nd amendment blocks obama from being elected president, but he could still become vice president and then become acting president through the process below.

#2 in the article's "legal" path would not work as eloquently. The only person who can just pick a vice president is the president.

The more legal route would require the 25th amendment on biden (or he could just simply step down) thus elevating kamala to president. Then she could nominate obama as her vice president. He would then need to be confirmed in the senate by a simple majority. It would take only one rino to commit political suicide to fully confirm him as vice president. Then kamala could get the 25th amendment on her (or just simply step down) elevating obama to president unelected (avoiding the 22nd amendment) allowing him to serve as president until the end of the term. Oh and he gets to pick a vp.

Should the two dopeheads in charge of the executive not want to simply step aside, triggering the 25th amendment would have an incredibly high bar needing 2/3rds of congress (house and senate) should the process fully play out.
