Democratic party leaders are already planning to re-take the White House in 2020 or 2024 (depending on how Trump's first term goes), by using their largest remaining asset, Michele Obama. The easiest way to stop her is to clarify that the 22A includes SPOUSES. It was passed right after World War II, in response to FDR's unprecedented 4 terms (the 4th cut short by his death), when nobody believed that a woman could become president. Well, that ship has sailed so we have to make sure that we do not turn into a banana republic and subvert our own Constitution thru such a ruse as spousal succession. I think Michele would make a fine president but this isn't about her per se, it is about preserving de facto term limitations for POTUS. I think the American people sense that HRC was overstepping by trying to serve a third term, which is why her own party rejected her in 2008 and the national elector sent her home in 2016. Granted the discussion was personal, about her lying and being part of the establishment, rather than on the principle of term limitations. But now that the smoke is clear, we should act. (I'd like to include parents-children and siblings as well but that is more of a stretch than husband-wife as the former do not share a bed.)
We should also consider creating a new body, sort of like a grand jury, that vets people BEFORE they are allowed on presidential ballots regarding age, non-spousal relationship to a 2 term prez, and birth. I'm thinking 105 people drawn randomly from the population, 2 from each state, the District, and PR, plus one at large to preside and break any ties. This is so we do not ever have the embarrassment of electing someone ineligible.
