Kamala Harris said Joe was sharp and up for the job.
They said the same thing about Reagan whose staffers admitted in later years that the effects of Alzheimer's were very pronounced during his last two years.
They said the same thing about Eisenhower even after he had a heart attack in 55 at age 63 during his first term in office.
They said the same thing about George H.W. Bush age 66 who had to be treated for atrial fibrillation while serving in office.
They said the same thing about Roosevelt (62) in 1944 when the knew that he had both hypertension and stomach cancer.
And they said the same thing about Donald Trump (78) who still hasn't released a full medical report describing the overall condition regarding the health of a 78 year old man.
So what does this tell you? The American presidency is a young man's job that requires the passage of a bill that limits both the number of terms as well as age limits for all high ranking public positions and offices.
