I think the JFKJR signaling is compelling.
Q1709 and Q179 included (delta between Dan's orig and POTUS rt).
I should analyze more first, then make graphic.
"dead" twice?
JFK Jr birthday encoded in the prior tweet? (added to delta between making "Q R JFK")
President for 5 more years? (then who?)
Maybe I'm way off and not ANY of this is related, but…
