As per Scooba's request, I did some research...

Abraham Lincoln was elected to Congress in 1846.
true
John F. Kennedy was elected to Congress in 1946.
Nope, 1947, same year as Nixon

Abraham Lincoln was elected President in 1860.
Yep, Nov. 6, 1860
John F. Kennedy was elected President in 1960.
True

Both were particularly concerned with civil rights.
Aren't all major political figures concerned with civil rights?

Both wives lost their children while living in the White House.
Partially true, both lost a son while serving in office

Both Presidents were shot on a Friday.
True
Both Presidents were shot in the head.
I don't wanna get into this. I'm enough of a conspiracy theorist... how is it possible that a bullet fired at Kennedy on a downward trajectory that entered (according to the marks on his clothing) below the shoulder line exit his throat? I dunno.

Now it gets really weird.

Lincoln's secretary was named Kennedy.
Kennedy's Secretary was named Lincoln.
I dunno where to find this information

Both were assassinated by Southerners.
True
Both were succeeded by Southerners named Johnson.
True

Andrew Johnson, who succeeded Lincoln, was born in 1808.
True
Lyndon Johnson, who succeeded Kennedy, was born in 1908.
True

John Wilkes Booth, who assassinated Lincoln, was born in 1839.
Nope, John Wilkes Booth was born on May 10, 1838
Lee Harvey Oswald, who assassinated Kennedy, was born in 1939.
True, but did he really kill Kennedy?

Both assassins were known by their three names.
True
Both names are composed of fifteen letters.
Also true, but considering the birthday thing was wrong, it's not really relevant
Now hang on to your seat.

Lincoln was shot at the theater named 'Ford.'
True
Kennedy was shot in a car called 'Lincoln' made by 'Ford.'
True

Lincoln was shot in a theater and his assassin ran and hid in a warehouse.
Kennedy was shot from a warehouse and his assassin ran and hid in a theater.
Who knows

Booth and Oswald were assassinated before their trials.
True

And here's the kicker...

A week before Lincoln was shot, he was in Monroe, Maryland
True
A week before Kennedy was shot, he was with Marilyn Monroe.
Bluetoy's account was probably more accurate
