First Dogs: Buddy and Truman
Let’s face it: it was a long shot; I put the words Harry S Truman and Pete Buttigieg in a Google search, and got this image (after more than a hundred other images of Pete Buttigieg alone).
But it tells me that, even unconsciously, Pete has a connection to Truman.

On the surface, the reversed North/South Nodes, between Truman’s death chart and Pete’s birth chart, signify a karmic connection. The only (almost) ‘exact’ conjunction is Pete’s natal Saturn and Truman’s ‘fatal’ Uranus. The rest are close, but no cigar. There is one inconjunct connecting Truman’s ‘fatal’ Sun with Pete’s Ascendant @ 3° Leo 39′. But is that enough?

Again, comparing their birth charts show close connections but hardly any direct hits: only Pete’s Saturn is less than half of a degree from Truman’s North Node @ 22° Libra.
My inspired guess is perhaps on shaky ground, so I’ve combine Truman’s birth and death charts with Pete’s birth chart to see what the overview shows us.

So, not totally conclusive of reincarnation, but certainly suggestive of similar thinking about atomic weapons:
Deterrence…
