Buttigieg could be the 1st of best POTUS in the 21st Century

Note here that Pete Buttigieg's "5-sister" connect matches the majority of past Presidents -- and he's on a level with:
POTUS32 Franklin D. Roosevelt
POTUS36 Lyndon B. Johnson elevated into office by an assassination 
POTUS37 {Republican screw-up} Impeached into a resignation NIXON
POTUS38 {Republican screw-up} elevated by Nixon Resignation
POTUS41 & 43 {Republican screw-up} the Bush clan that Love War did NOT help America and triggered 18+ years of war and wasted over Three Trillion Dollars murdering foreign civilians
POTUS44 Barack Obama

NOTE that the "ELECTED" 5-sister DEMOCRATS are the best of the modern era.
On a more recent level (post-1575) Pete Buttigieg is a "Jonathon's POTUS Cousins" {Amazon, January 2017} consistent candidate while Donald Trump is NOT a Potus Cousin -- as the chart shows, Trump's just a descendant of the 5-sisters and on a par with Warren & Biden.
