It wouldnt surprise me if Chadwick did NOT do a final tweet to vote for Depends/Kneepads, one of his Trump-hating lackeys actually did the tweet and lied about it.
He was probably EXTREMELY weak, cognitively impaired and in a coma weeks before he died. Ive watched people die from cancer, AIDS, and congestive heart failure. Such deaths are slow, merciless processes ending (usually) in incoherence, dementia and coma.
If there was a Marvel comic superhero whose special power was lying without a second thought ... we I suppose his name would be Captain US Lefty
