There are some broad commonalities of the inauguration charts of presidents who have died in office. I don't know how many other inauguration charts also look like this, but these eight charts are marked by close, malefic luminary and angle contacts.

William Henry Harrison was inaugurated March 4, 1841. (All of these are for Washington, DC and for noon). Moon-Mars sq. 0°03'. Saturn 0°17' from Descendant, mundane square Sun moderately.

Zachary Taylor was inaugurated March 4, 1849. It has a Moon-Saturn mundane sq. 0°26'.

Abraham Lincoln's second inauguration was March 4, 1865. Moon-Mars conj. 0°36'. The always-culminating Sun is sesqui-square Saturn 0°36'.

James A. Garfield was inaugurated March 4, 1881. Moon squared Mars 1°35'.

William McKinley's second inauguration was March 4, 1901. Neptune is 2°08' from Asc conjunct Pluto, while Moon-Pluto are in 0°33' mundane square (foreground).

Warren G. Harding was inaugurated March 4, 1921. The mundoscope is fascinating with a foreground Sun-Jupiter-Pluto T-square nearly partile a 1°39' Moon-Saturn mundane square.

Franklin D. Roosevelt's fourth inauguration was January 20, 1945. Mars is 0°54' from MC as the main feature.

John F. Kennedy was inaugurated January 20, 1961. Neptune was 0°16' from Descendant with a wider than usual Moon-Pluto mundane opposition (2°32').

Simplifying the visual presentation and dropping wider "of interest" contacts - to make the patterns more obvious - we get:

1. Moon-Mars sq. 0°03'. Saturn 0°17' from Dsc.

2. Moon-Saturn sq. 0°26'.

3. Moon-Mars conj. 0°36'.

4. Moon-Mars sq. 1°35'.

5. Neptune 2°08' from Asc. Moon-Pluto sq. 0°33'.

6. Moon-Saturn sq. 1°39'.

7. Mars on MC 0°54'.

8. Neptune on Dsc 0°16'. Moon-Pluto opposition 2°32'.

A couple of these have orbs wider than the rest. All have Mars, Saturn, or Neptune on an angle or in dynamic aspect with Moon within 2°07'. (More than half are partile.) When the planet was Neptune, it was supported by Pluto.

This pattern having been documented, it's worth noting that the 2021 Inauguration chart has a 0°36' Moon-Mars mundane conjunction. A secondary factor is Pluto 2°24' from Midheaven. (Moon is also conjunct Uranus 0°53' mundo).

As mentioned above, I haven't calculated all of the inauguration charts to get a baseline. I don't know how many charts match the above pattern and the president did not die in office. I do know, though, that this partile Mars contact is a direct match of half the cases where the president died in office, and matches the larger (only slightly more complicated) picture that all eight match.

Of the four who died under inauguration charts where Mars was the factor, two were assassinated and two died from illness, so there is no distinction on that.
