The Adams-Bush... Coincidences?

The Adams-Bush... Coincidences?

⦁ These were the only presidents to follow one another as father-and-son presidents.
⦁ Both couples were differentiated by a middle name or initial. Both father-presidents were VP's of charismatic conservatives that came before them, and were followed by charismatic leaders of the opposing party (both named "Jefferson")—each father serving just one term.
⦁ Both fathers started into a new decade and had a son start into a whole new century.
⦁ Adams' "A" is before Bush' "B".
⦁ George Bush, Sr. and John Adams, Sr. were both born in Norfolk County, Massachusetts.
⦁ Both sons had a VP whose last name began with a "C" and a wife whose first began with a "L".
⦁ Fate must not like sons to follow their fathers as pres., because neither son had a majority of the country's support—John Q. Adams was elected by our Congress!

⦁ Both sons failed to receive a plurality of the popular vote in their elections.

⦁ Both fathers ran for a second term, but was defeated by a southerner.
⦁ Both sons were elected over a Tennessean whose first name starts with the letter “A” and has six letters.
⦁ Both sons were born in July.
